How to choose and compare analysis software! Comprehensive explanation of recommended software

Here.Strength Analysis　Software that can performAnalysis software."It is a note about.

Many people are considering the introduction of "analysis software" in the field of product design, but are faced with so many choices that they are not sure which one to choose.　　Since many software products are expensive, we want to avoid making mistakes and having regrets.

While many comparison sites tend to limit themselves to individual software introductions, this article focuses first on getting the big picture by organizing the basic types of analysis software and their respective roles.　　Then, we note information to help you choose the best recommended software for you, including an exhaustive comparison of major software, price ranges, and finally, specific precautions to avoid mistakes after implementation.

Understand the basics and types of analysis software

The first thing you want to know about is the type of analysis software

Analysis software, or CAE (Computer Aided Engineering) tools, are software used to simulate the performance and behavior of products on a computer.　　By introducing this software, the number of physical prototypes can be significantly reduced, shortening development time and lowering costs.

Let me put it this way,Analysis software can be broadly classified into two types.　One is a "3DCAD add-in simulation tool" and the other is "simulation-only software.

3DCAD add-in simulation tool (designer CAE)

This is an analysis tool that functions as an integrated part of the 3D CAD software that designers normally use.　　The greatest advantage is that design and analysis can be performed seamlessly within the familiar CAD operation screen.　　Design changes are immediately reflected in the analysis model,This is very effective for speedy verification of various design proposals in the early stages of development.　Mainly for designers who want to perform relatively simple linear structural analysis easily.It can be said that

Dedicated simulation software (specialist CAE)

This is specialized software that specializes in simulating specific or multiple physical phenomena with high accuracy, such as structural analysis, thermo-fluid analysis, and crash analysis.Compared to the CAD add-in type, it has more functions and allows more complex and realistic condition settings.For example, it can handle nonlinear problems with very large material deformation, or coupled problems where heat and structure interact.　　Therefore, it is considered to be for professionals (analysts) in the R&D department who are required to guarantee the final performance of the product or to perform extremely advanced analysis.

Software and learning for beginners

For beginners who are new to analysis software or are just starting to learn, the best software depends on your objectives.

If you are a designer and want to validate your design easily, start with a CAD add-in type tool　It will be.　　For example,SOLIDWORKS Simulation　and ... andAutodesk Inventor Nastran　、　Fusion 360 Simulation　These include　　These are integrated with CAD, making them intuitive and easy to operate and keeping learning costs low.　　In particular, the domestically produced softwareFemtet　is an attractive option for beginners because of its extensive Japanese-language tutorials and low-cost access to a wide variety of analysis functions.

JapanICAD-SX (iCAD Corporation)　Now, there is no simulation in the CDA itself, but Fujitsu offersCOLMINA CAE　and ... andJupiter-Designer for iCAD　will make the analysis possible.

On the other hand, open source software is recommended for students who aspire to become analysis specialists in the future, or for those who want to learn serious analysis methods without the cost.　　Among themCalculiX　is a high-end commercial softwareAbaqus　and the input format is similar, so the knowledge gained here will be useful when transitioning to specialized work in the future.

The basic method of learning is to first utilize the official tutorials and training materials published by each software provider.　　Many vendors offer free seminars and webinars, so it is also a good idea to attend these.　　In addition, open source software has an active user community, and by asking questions in online forums, you may be able to get advice from experienced users.  

Basic functions at the core of the software

Analysis software has a wide range of functions, but at its core are three basic functions: preprocessor, solver, and postprocessor.

The preprocessor is a function that prepares the data for analysis. Specifically, it reads geometry data created in CAD and divides it into a collection of small elements called a "mesh.　　Then, the physical properties of the material (Young's modulus　and ... andPoisson's ratio　The role of the product is to define the boundary conditions (e.g., where the product will be subjected to force and where it will be fixed).

The solver is then the calculation engine that solves the equations of the physical laws based on the model and condition set created by the preprocessor.　　This is the heart of the analysis software, and the solver's performance greatly affects the accuracy and calculation speed of the analysis.

Finally, the post processor is a function that visualizes the enormous amount of calculation results calculated by the solver in a way that is easy for humans to understand.　　It can display in colors (contour diagram) where the greatest stresses are generated in the product and animate the deformation.　　This allows designers to intuitively identify weak points in the product and consider improvement measures.

Overview of basic structural analysis

Structural analysis, one of the most widely used functions of analysis software, predicts how a product will deform and what internal stresses will be generated when a force is applied to it.　　This allows us to evaluate whether the product can be used safely without breaking or whether it is too robust (is there room for weight reduction?).

Linear static analysis is the most basic type of structural analysis.　　This analysis assumes a situation in which a material is deformed but returns to its original shape (elastic range) and a force is applied slowly.　　This analysis can be easily performed with many CAD add-in tools, and is very effective in confirming strength in the early design stage.It is.

On the other hand, "nonlinear analysis" is required when materials deform so greatly that they cannot be restored to their original state (plastic deformation) or when dealing with materials that stretch and contract greatly, such as rubber.　　Dynamic analysis" is used to simulate phenomena in which large forces are applied in a very short period of time, such as a car collision or a falling smartphone.　　These advanced analyses are mainly the domain of dedicated simulation software.

Free and open source software

While expensive commercial software dominates the market, in recent years there has been a growing presence of open source analysis software that is available free of charge.　　The greatest advantage of these is that they do not require any licensing fees, making the hurdle to introduction extremely low.

However, there are some caveats.　　Open source software is basically used at your own risk, and you cannot expect the kind of extensive vendor support that you would get with commercial software.　　If a problem arises, you will need to read the documentation yourself or search for a solution in the user community.　　Also, the operability of the software may not be as intuitive as commercial software, so a certain level of specialized knowledge tends to be required.

Nevertheless, its capabilities are very powerful. Typical open-source structural analysis software includes

• CalculiXAbaqus: Developed in Germany, this software is similar in input format to the commercial Abaqus software, making it ideal for learning purposes.  
• Code_AsterEDF: Developed by EDF, a French electric power company, EDF has extensive experience in the field of civil and plant engineering in particular.  
• OpenFOAM: Although it is mainly known for fluid analysis, this toolbox can also be used for structural analysis and coupled fluid/structure analysis.   

These software programs are a very valuable option for individuals who want access to advanced analytical techniques without the cost, or when customization is required for a specific research application.

Thorough comparison of major analysis software

Price range of major software at a glance

The price of analysis software varies widely depending on its features and licensing format.　　Here we divide the major software into two categories and provide a comprehensive comparison of their features and price ranges. However, prices vary depending on configuration and contract type, and should be used as a guide only. For accurate information, we recommend that you contact each manufacturer or distributor directly.

• 3DCAD add-in simulation tool (designer CAE)

This tool allows designers to easily perform analysis in a familiar CAD environment. Intuitive operability and quick design verification are attractive features.

• Dedicated simulation software (specialist CAE)

High-performance software for professionals, specialized for analyzing specific physical phenomena and complex problems with a high degree of accuracy.

Share and Trends by Industry

While it is difficult to find uniform and accurate public data on the industry share of analysis software, it is possible to infer a power structure from industry trends and the position of each software product.

In the global market as a whole, Ansys, Dassault Systèmes (Abaqus), and Siemens (Simcenter) are the so-called "Big 3" market leadersThese companies are the leading global providers of manufacturing solutions for the automotive, aerospace, and electronics industries.　The comprehensive platforms offered by these companies have been widely adopted by major manufacturing industries such as automotive, aerospace, and electrical.　　Ansys, in particular, is valued at approximately $32.9 billion in market value as of September 2025, which is a testament to its significant impact.

In the automotive industry, LS-DYNA has long been the de facto standard for crash safety analysis.　　In the aerospace industry, Nastran (especially MSC Nastran), with its historical background of development at NASA, remains highly trusted for vibration analysis.  

Looking at Japan, while global software has a high market share, domestically produced software is also showing strength in certain areas. For example, TechnoStar's Jupiter has established a strong position in the Japanese automotive industry for its ability to process large models at high speed. Murata Software's Femtet is also widely used by designers, especially in the electronic components industry, due to its cost performance and ease of use.  

A recent trend is the "democratization of simulation.　　This refers to the movement toward the use of analysis tools not only by analysis specialists, but also by designers themselves.This trend has led to a growing market for CAD add-in tools such as SOLIDWORKS Simulation.　Another notable trend is the emergence of cloud-based simulation services, which are being adopted mainly by small and medium-sized enterprises (SMEs) due to their ability to use high-performance computing resources while reducing initial investment.

Real reputation by users

In selecting software, it is very important to refer not only to catalog specifications but also to the reputation of actual users.

3DCAD add-in type simulation tool

Software in this category is generally highly rated for its "ease of operation" and "linkage to CAD.　　SOLIDWORKS Simulation and Inventor Nastran, in particular, allow analysis as an extension of the CAD software that is normally used, and many say that "learning costs are low" and "design changes can be reflected smoothly.　　The Japanese product Femtet has been highly evaluated for its "low cost and multifunctionality" and "generous Japanese-language support," and is particularly popular among designers at small- and medium-sized companies.  

However,One disadvantage is that advanced analysis capabilities are limited compared to specialist software.　There may be situations where you may feel a lack of functionality when dealing with complex nonlinear problems or special materials.

Software dedicated to simulation

Professional software such as Abaqus and Ansys have earned tremendous trust for their "high analytical capability" and "rich functionality.　　In particular, Abaqus has received numerous evaluations for its ability to solve problems that could not be solved with other software, especially in nonlinear analysis of complex material behavior such as rubber.　　Ansys is highly regarded in the field of multiphysics analysis, which links multiple physical phenomena such as structure, heat, fluid, and electromagnetic fields.

On the other hand, the rich functionality of these software products makes them difficult to learn to operate, requiring "specialized knowledge" and "training is essential to master.Some people say, "I'm not sure I want to do this.　　Another major hurdle to introduction is the extremely high cost of licenses.

List of notable domestic software

As global software dominates the market,Domestically produced analysis software, which has evolved in response to the on-site needs of the Japanese manufacturing industry, also has its own unique strengths.　Here are two domestic software programs of particular note.

Jupiter (Technostar Corporation)

Jupiter　is a software that is especially good at analyzing large, complex models.　　It provides fast mesh generation and comfortable operability even for huge models with more than tens of millions of degrees of freedom, such as an entire automobile engine or a whole car body.　　The software is widely used by Japanese automobile and parts manufacturers, who have reported dramatic productivity improvements, such as a "70% reduction in meshing man-hours" and a "3-fold increase in the number of design reviews.　　The developer, which has extensive knowledge of the Japanese manufacturing industry, has also been highly praised for its detailed support system.  

Femtet (Murata Software Co., Ltd.)

Femtet　is a unique software that has been developed by Murata Manufacturing, an electronic components manufacturer, as a commercial version of a simulation tool that it has been improving for its own product development for many years.　　Its greatest feature is that it combines "multifunctionality," "easy operation," and "low cost" at a high level.　　The software comes standard with eight types of analysis functions, including stress, thermal, fluid, electromagnetic, and acoustic, and is priced from approximately 240,000 yen per year, making it very easy to introduce compared to software for specialists.　　It is used by many companies as a tool that can be used not only by analysis specialists but also by designers themselves on a daily basis.  

Reference case studies

Knowing how the software is actually being used and what results are being achieved is very useful when considering implementation, and we note the information we have researched below.

In the automotive industry, many companies use analysis software to compete in development.　　For example, companies such as Toyota Motor Corporation, Honda Motor Co.Ansys　The company has also introduced the "Simulation System for Automotive Design" to improve development efficiency by utilizing simulation from the early design stage.　　In addition, to ensure collision safety of automobiles,LS-DYNA　Crash simulation using the "CRASH" method has become an indispensable process, and is also used to analyze the deployment behavior of airbags.  

In the aerospace industry,Abaqus　is being used to evaluate the strength of composite materials and the durability of engine parts.　　Abaqus, which is capable of highly nonlinear analysis, was chosen to meet the extremely high requirements of both weight reduction and safety of flight vehicles.   

The use of analysis software is expanding in the consumer electronics and precision equipment industries.　　At Fujifilm Business Innovation,Abaqus　The paper transport mechanism of printers is simulated using a simulation system to prevent paper jams and other problems before they occur. Many consumer electronics manufacturers use simulations to evaluate the drop impact resistance of their products and noise and vibration during operation, leading to improved product quality.   

As these examples show, analysis software has become an indispensable tool for modern manufacturing, contributing not only to simply confirming the strength of a product, but also to optimizing performance, shortening development time, reducing costs, and even creating new value.

How to choose the best analysis software

Advanced nonlinear and coupled analysis

In product development, advanced analysis capabilities may be required to predict behavior closer to reality. Typical examples are "nonlinear analysis" and "coupled analysis.

Nonlinear analysis is required in three main cases.　　The first is when a material undergoes plastic deformation (deformation that does not return to its original state after the force is removed).　　This is the case, for example, with metal press work.　　The second is when handling materials such as rubber and resin, which deform greatly with little force.　　The third is when accurately simulating the behavior of members contacting or separating from each other.　　For these analyses, software such as Abaqus and Marc have a long track record and high reliability.

Coupled analysis is a method for solving problems in which multiple physical phenomena interact with each other, such as thermal and structural, fluid and structural, and electromagnetic and thermal.　　For example, complex problems can be simulated in which the heat generated by the motor causes deformation of the components, which in turn affects the performance of the motor.　　Integrated analysis platforms such as Ansys, Simcenter 3D, and COMSOL Multiphysics provide powerful solutions to such multiphysics problems. By mastering these advanced analyses, it is possible to discover issues that would not be revealed by a single physical phenomenon alone and dramatically improve the reliability of your products.

Comparison and selection guide by purpose

The key to choosing the best one among the many analysis software is to clarify "who," "what," and "at what level" you want to analyze.　　Here are some guidelines on how to choose one for different purposes.

Case 1: Designer wants to check basic strength in the early design phase.

In this case, an add-in type tool integrated into the 3DCAD currently in use is most efficient.SOLIDWORKS Simulation is the first choice for SOLIDWORKS users, and Inventor Nastran for Inventor users.　　Data linkage with CAD is smooth, and strength can be evaluated quickly with repeated design changes.

Case 2: An analysis specialist wants to guarantee the final performance of a product.

For this purpose, professional software with high analytical accuracy and rich functionality is essential.　　Abaqus is the preferred choice for nonlinear analysis of complex materials such as rubber and composites, while Ansys shows its strength when the main task is coupled analysis involving multiple physical phenomena such as heat, fluid, and structure.　　In addition, MSC Nastran has traditionally been chosen when high-precision vibration and noise analysis is required in the automotive and aerospace fields.

Case 3: Want to try different types of analysis while keeping costs down

For designers who are not bound to a specific CAD system and want to try a wide range of analysis such as structural, thermal, and electromagnetic field analysis easily, we offer a Japanese-madeFemtet　is a very attractive option.　　It allows you to implement a multifunctional analysis environment at an unbeatable cost-performance ratio.

Case 4: Students and researchers want to use it for learning and researching analytical techniques.

Free and open source software is the best choice for this tier, where cost is the biggest constraint.　　CalculiX is a powerful tool for learning the basics of FEA, while Code_Aster is a powerful tool for advanced civil engineering and plant-related studies.　　Most commercial vendors also offer free or inexpensive academic licenses, so taking advantage of these is also a viable option.
