Rapid Software Prototyping – All you wanted to Know!

In the process of software development, activities of rapid prototyping software are very important. Creation of software prototypes for testing works of the software is extremely important. It should be noted here that prototypes are nothing but incomplete versions of software program, which are in the process of development. 

What is the working process of Rapid Prototyping Software?

In this kind of software, the mock-up developed does not perform the software’s functional spectrum. It just stimulates some of the features or aspects. 

Why this software?

This software helps users of eventual software to evaluate the design proposals provided by the developer. Users can try out the simulations themselves. Why? This will help them to get a firsthand sense so that they can make a judgment. Therefore, the users don’t need to make an evaluation decision on the basis of program descriptions only. 

Developers may not have thought of certain things that users may think something to be useful. This software allows users to bring some of these aspects to the notice of developers. It not only improves the end product but also helps in the betterment of the commercial relationship between the solution provider and client. 

What are the Benefits?

There are various benefits associated with Rapid Prototyping Software and they include:

1. One of the greatest advantages of rapid prototyping software is that the software implementer as well as the software designer obtains feedback from the users directly. The users will use the final product. While using this software, the users will come across certain requirements that a developer or designer may not think of. Once these requirements are passed on to the developers, they implement those aspects in the final product. Ultimately, the final product becomes a better one.

2. The software engineer gets a chance to check the accuracy extent of the initial project. Therefore, the person can actually find out if the milestones as well as deadlines can be achieved within specified time.  

These are the two most important benefits of rapid prototyping software.

Dynamic Mechanical Analysis – Operating Principle

In case of modern polymer laboratory, dynamic mechanical analysis is an important too. Despite of the immense importance of DMA, only a few journals and books have concentrated on this technique. The first ever experiment with this technique used oscillatory method. This was first done in the year 1909. With the progress of science, this technique also got user friendly. 

To get an idea on the recent developments on the DMA technique on polymer, let us discuss about the operating principles. According to this principle, a sample will deform sinusoidally if a constant load that is applied to the same starts to oscillate in a sinusoidal manner. In case, deformation of the sample material gets deformed within the linear viscoelastic region, it will be reproducible. 

Now, let us define the stress applied with the help of an equation:

σ =σ₀ sin ωt      -> Equation 1

t refers to time

σ refers to stress at time ‘t’

σ₀ refers to maximum stress

ω refers to frequency of oscillation

If you want to know the stress rate, then it can be found out through the derivative of the Equation 1, mentioned above. In terms of time ‘t’, stress rate is written as:

dσ/dt = ωσ₀ cos ωt

The strain wave can be determined by summing the limiting extremes of the material, namely, viscous and elastic. If you evaluate the two extremes, the behaviour can be understood. With the oscillating stress, Hookean limit of the material (also referred as spring like limit) will respond elastically. 

Strain at time ‘t’ is: ε (t) = E σ₀ sin (ωt)      

In case of linear region, ε and σ are related linearly by E. This is the reason why strain at time ‘t’ can also be written as ε (t) = ε₀ sin (ωt). Please keep in mind that ε₀ is nothing but strain at the extreme condition of maximum stress.  

Now, let us find ε (t) in terms of viscosity, η. 

Therefore, ε (t) = η ωσ₀ sin (ωt + π/2)

  If term s is substituted, the equation becomes:

ε (t) = ωσ₀ sin (ωt + π/2)

Now, let us find out elastic time at any point of time, say ‘t’. The equation will be:

ε (t) = ε₀ sin (ωt + δ), where δ is an angle that is the difference between applied stress and resultant strain. Δ is needed to be added to equations. 

Let us learn about the in-phase as well as out-phase strains in the operation of Dynamic Mechanical Analysis (DMA). In-phase and out-phase can be written as ε’ = ε₀ sin(δ) and ε” = ε₀ cos(δ) respectively. 

Complex or overall strain can be written as:  ε* = ε’ + iε”.

Operating principle of the Dynamic Mechanical Analysis can be explained through these equations, mentioned above.

All about Incremental Dynamic Analysis Procedure

Incremental Dynamic Analysis, popularly known as IDA, is a special type of seismic or structural analysis method. It is basically an all-in-one computational assessment that has been extensively used in the field of Earthquake Engineering for identifying as well as analysing the dynamic behaviour of structures under different types of seismic loads. The process was developed with the intention of providing comprehensive solutions to huge structures in case of severe seismic hazards. 

Objectives of IDA

IDA is known as the perfect dynamic alternative to the well-known static pushover analysis method. The major objective of this process is to help engineers detect potential seismic risks that a specific structure might have to face in recent future. It also provides perfect solutions for eliminating those factors that can affect the structural designs significantly. 

About the Process of IDA

The entire process of IDA is a combination of more than a few nonlinear dynamic analysis techniques which are carried out carefully under several suitable conditions. At the same time, a number of ground motion values are recorded, and all of them are made compatible with different levels of seismic intensity. These levels of scaling are so selected that the structure under experiment can be put under a wide range of force. It helps those sample structures undergo phase change from elastic instability to global dynamic instability. 

The practice of IDA for large buildings and other rigid structures is highly efficient as they help engineers protect those constructions from potential damages. As a result, more and more organizations are relying on this procedure these days. However, the process of incremental dynamic analysis can be performed manually as well as with the help of advanced software applications. Using software for this purpose is more convenient than putting manual effort in it. That is why various software development organizations have developed lots of effective computer programs that can help dynamic evaluation greatly.

A Brief Introduction to Flexible Dynamic Analysis

Flexible dynamic analysis, also popularly known as time-history analysis, is a special analytical method used for identifying and evaluating the dynamic response of a rigid multibody system under the influence of any broad-spectrum time-varying load or force. In this blog post, we have discussed this special type of structural analysis procedure briefly. Take a peek into the following vital information:

• Typically, flexible or time-history analysis is used for calculating as well as analysing the time-dependent dislocations, stresses, and forces generated in a composite structure consisting of multiple rigid components as it acts in response to any type of static, transitory or harmonic loads. 

• The effects of inertia and damping properties of the structure are also taken into account by analysts while carrying out the analytical procedure. The time of loading is so adjusted that these two effects are balanced properly by the structure itself.

• Usually, the process of flexible dynamic analysis is divided into two categories: Linear Flexible Analysis and Nonlinear Flexible Analysis. When it comes to nonlinear time-history analysis, almost all types of nonlinearities can be used including hyper elasticity, plasticity, point-contact, small to large bends or deformations, etc.

• Flexible or time-history analysis involves a lot of computer works. Unlike static analysis, it needs a wide array of resources or preliminary data which can be fed to the advanced software application as input, for getting more precise output of the analysis. 

• However, flexible analysis of a multibody structure is an extremely time-consuming affair. Therefore, using a high-grade software instead of carrying out the entire procedure manually is always a good idea for the researchers. 

Flexible dynamic analysis can be used for determining the dynamic properties of different types of materials which is really helpful for engineers as well as scientists. That is why, the method has been gaining much popularity these days.

A Brief Introduction to Finite Element Analysis

Finite Element Analysis (FEA) or Finite Element Method (FEM) is one of the most significant analytical approaches used for solving complicated stress problems numerically. With the help of good-quality finite element analysis software, the entire analytical process can be carried out successfully and the results can be obtained in a very short time. 

Various Steps of FEA

When computer programs are used for conducting finite element analysis, the entire method becomes much easier as well as less time-consuming. There are basically three steps involved in the procedure. Read on below to know about them:

• Pre-processing: In this stage, a model is prepared by the analysts at first and then geometrically subdivided into numerous regions. Each of those regions is given the name ‘finite element’ and the discrete points at which they are attached to each other are known as ‘nodes’.

• Solution / Analysis: The experimental model used in this method consists of the most easy-to-use graphical pre-processor which helps in preparing the requited sets of data. This data works as the input to the finite element analysis software, and helps analysts generate and solve certain sets of linear as well as nonlinear algebraic equations. 

• Post-processing: Like pre-processor, the experimental model also consists of a post-processor that is used for analysing the results obtained from the system of equations, and validating the data as well. 

Advantages of FEA

The method of FEA has become extremely important to the researchers worldwide. They are using it extensively for improving the designs and functionalities of CAD models. Cost-effectiveness is another great benefit of this procedure. That is why; more and more organizations are leaning towards this method recently. In addition, analysts can also save their valuable time and efforts to a great extent by making use of high-quality finite element analysis software.

Basics of Kinematic and Dynamic Analysis

"Motion study" is an umbrella term used for stimulation and analysis of movement in machines. The term described above can be categorised under two heads: dynamics and kinematics. Kinematics can be defined as the study of motion (forces causing the motion is not included in the purview of this study) while dynamics deals with the forces that have resulted the motions. Multi-body dynamic analysis is closely related to this discussion. Kinematic Analysis Kinematic analysis is not as complex task as dynamic analysis. It shows the physical position of different rigid bodies, working as a single unit (machine), with respect to time. The technique is very help in the process of assembly of different machine parts. It can also provide reaction forces (generated from the motion). Dynamic Analysis In dynamic mechanical analysis more details are required. It needs more data for the calculation and prediction of forces. The advantage of the process lies in its accuracy. It shows results that are closely relevant to the actual performance of a mechanical system. In general term, the dynamic simulation analyses the function of a mechanical system while kinematics simulation is used for evaluating its form. Preparation and analysis of data in both the cases is done with the help of software. In present days, programs have become more interactive with more features. How the System Works Workable designs are developed by stimulating a mechanical setup. The movement of rigid bodies are rendered an animated form. This helps in understanding different forces working in the system. Design engineers use this modelling for identification and rectification of problems. Dynamic analysis helps in determining inferences among different moving parts and correcting the faults. A mechanical system can also be checked by incorporated number of unrelated parts into the system with the help of dynamic analysis. The technique has been very useful for development and modifications of machines.

How Distributed Multibody Dynamic Analysis and Product Development are Related to Each Other

With the extensive advancement of technology, each and every aspect of the innovation process is getting enriched significantly. The same is true for the Product Development Process (PDP) also. These days, engineers are applying the distributed multibody dynamic analysis method for improving the entire procedure of PDP. The latest framework is a unique one and is based on an online distributed Multibody Dynamic Simulation (MBS) or eMBS platform.  What is distributed MBS system? Distributed Multibody Dynamic Simulation is closely related to the process of dynamic mechanical analysis. It is quite different from the traditional client-server system which is used for satisfying the needs of customers. It actually offers an excellent solution for analyzing the dynamics of different structural bodies by distributing the process of multibody dynamic simulation suitably. In this system, end users can choose a particular simulation model as well as successive values for using as input parameters. They can also select the result values as per their requirements and use those as output parameters. Depending upon the input and output values supplied by the clients, the internal software generate the desired outcomes.

Application of the system The major application of distributed multibody dynamic analysis is found in vehicle systems. With the help of this analytical framework, engineers can easily understand how exterior forces can regulate the movement of diverse structural bodies. It plays the key role in distributing the complete simulation technique all the way through the product development process appropriately. Basically, the analysis or evaluation is done at different phases of PDP. In each of those phases, distinctive simulation models are used with dissimilar purposes. At the end, all analytical reports are synchronized accurately by using a web client and come the best possible solution is generated. However, researchers are still continuing their researches on how the influence of distributed multibody dynamic analysis on product development can be enhanced remarkably and coming up with better conclusions.

3 Important Software Prototyping Techniques

Software prototyping is one of the most vital software approaches taken by the developers these days. It needs the identification of fundamental prerequisites, development of initial prototypes, evaluation of the system capabilities, and enhancement of the overall system. Find below three most important techniques that are used for the prototyping of software applications:

•    Evolutionary prototyping: The major objective of this technique is to build a software system at first, and then improve it. It is usually used for those systems where the specification of the users’ requirements cannot be created beforehand. The evolutionary prototyping model is developed by the using the methods which deal with rapid system iterations. As there is no provision for developing specifications, earlier verification of the proposed systems is not possible. However, authentication of the anticipated software system is still feasible which refers to the demonstration of the competence of the system. Accelerated system delivery and better user involvement are two major advantages of this type of software prototyping. •    Throw-away prototyping: It is basically the procedure of developing a software model prior to the development of the final product. The method starts with an initial specification. A prototype is created from it, used for the testing, and finally discarded. This technique does not help in creating a final system. Rather, the prototypes developed through this practice lack certain system attributes, specifications for lasting preservation, and organized structures. However, they are able to lower the risks associated with requirements of the users. •    Incremental development prototyping: Incremental development approach is quite different from the other two techniques. In this software prototyping model, the final software system is developed as separate prototypes. As the name suggest, the overall design of the anticipated system is developed as well as delivered in an incremental fashion. Specifications as well as requirements that are needed for each increment are created stepwise, and potential users are allowed to experiment with them accordingly. Among all the aforementioned software prototyping techniques, incremental development is considered as the most advanced as well as effective one.

A Few Important Things About Dynamic Mechanical Analysis

Dynamic Mechanical Analysis or DMA is a thermo-analytical method that helps scientists collect necessary information about several mechanical properties of a specific visco-elastic substance. In this article, we will focus on a few vital things that we must know about this useful analytical procedure.

Effective factors Dynamic analysis of visco-elastic materials can be regulated by a variety of factors. There are different types of things that have huge impact on the analytical procedure and hence, must be taken into account while carrying out the same. These important influential factors are: the polypropylene material that is being used as the specimen (type of the sample, nature or behaviour of the sample, composition of the material, properties of the constituting elements of the material etc.), type and nature of the load or force applied to the specimen, the range of temperature in which the experiment can be conducted successfully, the range of frequency that is needed for the experiment, and the torque associated with the dynamic mechanical analysis procedure. Measurement There are several measuring techniques that are used for determining the dynamic mechanical properties of visco-elastic materials. However, all of them can be broadly categorized into following two types: •    Force-controlled techniques: Stress or force is the major controlling factor in this sort of experiments. Basically, a dynamic sinusoidal force is exerted on the sample which results in certain deformation in it. The objective of the test is to measure this deformation. •    Deformation-controlled techniques: It is a reverse method of the previous one. Here, a sinusoidal deformation is applied to the specimen instead of certain force or stress. The output of this type of experiment is obtained in the form of stress that can be calculated easily. However, while carrying out the procedure of Dynamic Mechanical Analysis or DMA, engineers need to be extremely cautious as the method is exceptionally quick to respond to the variations in the stiffness of a visco-elastic material.

Thermal Analysis - Basic Aspects and Advantages

When an engineer is going to design a product, he keeps many things in mind. However, one of the most important ones is the proper understanding of temperature distribution with the structure of the product. Proper understanding of the structure’s response towards thermal flux should also be there.     Thermal analysis is the process that helps in proper understanding of heat transfer modes. Through the development of models it is possible to understand the thermal response as well as performance of structures.

This kind of analysis becomes a must for wide range of industries, including consumer products, automotive industry, electronics items, energy and aerospace. There are many companies that provide this kind of thermal evaluation as well as analysis service. They generally have years of experience as well as thorough understanding of physics. They also have in-depth knowledge of the systems, involved in the design. Professionals of these companies have expertise in the development of the complex heat transfer simulations. Thermal analysis includes many services. Here, we will give a brief picture on that: •    Virtual prototypes and simulation are used to identify energy as well as hotspots. •    There may be certain factors that cause certain problems. Analysis of these factors is very essential. In addition to this, the issues regarding identification of design are also involved. That’s the reason why proper design evaluation of systems, products or buildings is very important. •    The services included in them are field testing processes as well as laboratory There is wide range of advantages associated with this type of analysis and they are: 1.    When a product is designed, the actual thermal risks associated cannot be understood properly. It can be done only when the prototype is built actually. Identification of the thermal issues can be done properly with the help of analytical services. This will ultimately help organizations to save lots of money as well as time. 2.    Stresses in components can be identified with the help of thermal analysis. 3.    Whether safety as well as product quality of the analysis is followed can be ensured with the help of this evaluation and analysis.

Dynamic Mechanical Analysis – Instrumentation and Applications

Dynamic analysis is a thermo-analytical technique that is widely used for measuring as well as evaluating the viscoelastic properties of polymers. Dynamic Mechanical Spectroscopy is a special type of dynamic simulation process that helps engineers study the behaviour of polymers more elaborately. Know about the instrumentation and applications of this procedure through this blog post. Instrumentation Dynamic Mechanical Spectroscopy, also known as Dynamic Mechanical Analysis or DMA, involves the use of certain advanced tools and equipment. The sample needs to be arranged as well as handled according to the property that is being measured by the procedure.  Clamps are required for holding the sample properly during the process. A displacement sensor is used by the engineers for performing DMA efficiently. A linear variable differential transformer would be the best choice for this purpose.When the probe of this sensor moves through a strong magnetic core, a change in voltage is sensed by it. In order to load the probe for providing the applied force, a linear drive motor is used.And, for directing this applied force to the sample from the linear drive motor, a drive shaft support as well as guidance system is used.A furnace or certain other temperature control system is also required for this dynamic analysis method.

Applications

DMA has different types of applications. However, we have mentioned two major of them here:   •    To determine glass transition temperature of polymers: With the help of this thermo-analytical procedure, different glass transition temperature ofamorphous polymers can be measured easily.If this temperature of a polymer is exceeded, the substance starts behaving like a rubber instead of a glass. •    To identify the composition of polymers: The quantity of monomers, by which a polymer is composed, can easily be determined by using DMA.Based on the percentage of constituting monomers, the properties of a polymer candiffer greatly. Aside from these two, there are many other applications of dynamic analysis. However, it varies depending upon the industries and their requirements.

Basic Knowledge of Multi-Body Dynamic Analysis

Before we jump in to discussing all about multi-body dynamic mechanical analysis, we need to learn the highlights of this analysis process.

          What Is It Actually? 

These applications are designed to focus on the dynamics of mutually interconnected rigid bodies. Trying to understand how these subjects work as a unit is the main function of such applications. This application analyses subjects while they are in function and it tries to register different kinds of forces that are discovered during the process.

Computers are obviously used to calculate these functions precisely plus, maintaining a stimulated environment that is important for the research. Researchers call this mechanism as- 'double rigid pendulum'.

Calculations of this Analysis

As we have already stated that computers are used to calculate the functions of interconnected subjects, now we are going to talk about how the computing movement of bodies influences the results. First of all, equations are used in calculating the functions and their result.

Calculating the motion feature of dynamic mechanical analysis is done by registering the current function results and comparing it with the previous ones. Computer first formulates the equations of motion and then uses previous valuable information to understand the relation between interconnected subjects. Equations regarding motion are integrated numerically with the help of DAE solver programs (DAE means Differential Algebraic Equation).

What It Offers?

These applications help people to find the relation between multi-body systems and how they work. These applications are designed to offer interaction conditions with multi-body subjects. Plus, it makes calculations in an automatic manner, so that the movement result can be returned to the administrator of machines. Here is a list of input data for these applications.

Input data

• Using mass as the rigid body to find results.

• Prescribed motions are checked and calculated.

• This application checks friction, spring, gravitational force, contact force, and other types of force units.

These are a few input data for dynamic mechanical analysis.

Benefits of Software Prototyping

Software prototyping is one of the most promising practices used by majority of the software development companies in Australia. In this technique, prototypes of software are made before the development of the final product. Software prototype is nothing but a sample of a complete software system which is used to test the entire process even before the formation of it. Here we have listed down some great advantages of the prototyping method as well as usage of software prototypes: •    The prototyping approach helps software developers win the confidence and reliability of clients greatly. They can create small prototypes of the desired software system and show it to the clients to know their opinions. Depending upon these models and their functionalities, clients can evaluate the capabilities of the developers and agree to work with them.

•    It is also effective for fetching prospective investors who can fund the new projects of software development. If the prototype model is liked by the investor, the developer might get funded for his or her upcoming project. •    A software prototype is shown to the user before creating the final software system. It allows them to develop an appropriate idea about the features as well as functionalities of the software that is going to be developed. Based upon those, users can also propose useful modifications for the same. •    The method of software prototyping is all about formation of certain software prototypes, assessment of them, and identification of potential risks associated with their applications. As a result, developers can take necessary mitigation steps for diminishing the chances of failure in future. These are some of the most important benefits of software prototyping that developers can take the advantage of. So, if you are a software developer, try using this method to come up with new innovative application software system.

Know in details about Vibration Analysis process

Vibration analysis is a process that allows interval at maximum level between repairing process and it is done by monitoring definite mechanical condition of rotating piece of any machine. Down time of machine is not sufficient for tracking these kinds of activities. In turn, effective monitoring minimizes expenses that are spent in order to handle different machine problems.

      Know about this analysis process in details:

The success of this kind of analysis is dependent on two essential facts. Firstly failure modes have distinctive vibration frequency elements that may be isolated as well as easily identified. Secondly the magnitude of vibration of each and every vibrating component will always remain constant unless there is any specific alteration in functional dynamics of a machine.

In nutshell, tracking of vibration of a machine offers correlation between machine’s condition and also data of vibration process of each and every machine that are effectively recorded. In other words vibration analysis Software can be used for identifying specific degradation of machine parts or any kind of minor failure of machine. This early detecting is helpful and allows the engineers to take early precaution before anything serious happens.

Normally eighty percent of mechanical problems that occur in machines are either due to imbalance or even due to poor alignment. Such conditions often cause other issues like premature bearing, shafting of seals and so on. Maximum of these problems also can be easily prevented to proper maintenance and protection. In addition such imbalance and alignment issues may even occur immediately after installation of new machine. And in order to handle such situation engineers often depend on this analysis process. That is to say, this process helps in checking that the new machine is properly installed. And in the initial stage this vibration analysis detects failure of machine thereby enhancing the productivity and longevity of the same device to a great extent.

How to Evaluate Polypropylene Impact Resistance by Dynamic Analysis

Impact resistance is a vital property of various plastic products (made of polypropylene or modified polythene) which is characterized by breakage under strains applied at high velocities. Dynamic analysis is considered as one of the most effective as well as suitable methods for calculating the impact resistance in polypropylene materials. Why DMA is used for evaluating impact resistance DMA or Dynamic Mechanical Analysis is a thermo-analytical technique intended for studying and differentiating the viscoelastic performances of polymers. Nowadays, it is vastly being used for measuring the capability of polymers to endure an abrupt impact. While the conventional evaluation methods of impact resistance are consistent and need prolonged sample preparation, DMA provides a swift, comprehensible alternative to them. It basically estimates the rigidity (scientific term ‘moduli’) and energy dissipation (scientific term ‘damping’) properties of polypropylene substances when they are distorted under sporadic tension. The results or data received in this way can be linked to the impact resistance properties of those substances for evaluating those features.

How the experiment is performed During the initial phase of the dynamic analysis, the sample propylene material is clamped and kept under horizontal motion by using an electromagnetic motor. The amplitude of the strain generated due to this motion can be varied by the engineer. A Linear Variable Differential Transformer (LVDT) is also connected with the sample in order to assess the response of the material under study to the applied strain.  When high speed is applied to the motor, the sample undergoes displacement which is known as ‘flexural deformation’. However, to obtain the perfect result, a preset frequency (usually the resonant frequency of the propylene material) is determined at which the dislocation of the sample is recorded. The outcomes of this dynamic analysis procedure are represented by graphical images. Those graphical curves are basically frequency and damping curves of the sample polypropylene material after it is modified.

A Brief Note on Thermal Analysis

Thermal analysis is a specialized segment of science that deals with the study of properties of different materials as they change with fluctuation in temperature.  There are several types of analysis methods that are popular in the present times. For instance, ‘Dielectric thermal analysis’ or DEA method is used for measuring dielectric permittivity while ‘Differential thermal analysis’ or DTA measures temperature difference. ‘Thermo optical analysis’, better known as TOA, is used for analysing optical properties. Another popular thermal analysis methodology, Simulation Thermal Analysis or STA refers to application of ‘Thermogravimetry’ as well as DSC or ‘Differential Scanning Calorimetry’ in simultaneous manner. 

     In simple terms thermal analysis process is widely used in order to indicate a specialized branch of study that analyses heat transfer process in different structures. Know the importance of this analysis in studying different materials or properties:

For analyzing pharmaceutical materials:

This type of analytical method is used for determining characteristics of different pharmaceutical elements. Differential Scanning Calorimetric method alone and also in amalgamation with hot staging microscopic process differentiates between several polymorphic structures. Making use of diverse heating rates, it also investigates transformation that usually occurs during transformation of polymorphic elements. It also helps in determining purity of polymorphic components. TGA methodology also is used for measuring residual solvents as well as moisture and also may be widely used for determining the solubility of different pharmaceutical elements in solvents. In fact this analytical study of different pharmaceutical materials forms the biggest part of thermal analysis application. 

For analyzing different metals

In production of different types of metals like ductile iron, copper alloys, steel, silver etc, this type of heat analysis plays a vital role. For example good quality liquid metal is effectively removed from furnace and then placed inside a cup where thermocouple is embedded. After that temperature is nicely monitored and also different types of phase diagrams are noted. Specifically speaking thermal analysis of metals is done effectively in case of metals.
