Introduction to Ansys
Background of Ansys
Ansys has been founded in 1970 and incorporated in 1994. Ansys predominantly offers engineering simulation software and ancillary services. The solutions provided by the company are used in a wide range of industries including aerospace, defence, automotive, biomedical and other industrial sectors. Ansys has been recognized as one of the world's most innovative companies by prestigious publications such as Bloomberg Businessweek and FORTUNE magazine for its engineering simulation software. Leveraging the power of today's Desktop, Ansys provides a common platform for product development, from design concept to final-stage testing and validation. The company's product portfolio consists of simulation platform offerings that are used in diverse multi-physics fields like heat transfer, fluid mechanics, statics, solid mechanics, etc. However, Ansys is best known for finite element analysis (FEA), which has gained popularity as a modelling and simulation tool over the years (and especially since the introduction of powerful computers) in solving a gamut of complex engineering problems. Ansys CAE software is popular with both academia and industry because of its multi-physics capabilities, thorough documentation and availability of training institutes that provide online and in-person Ansys courses. Since the ability to use Ansys software is a plus point, students too prefer getting certified in Ansys training.
The mainstay of Ansys is the Ansys Workbench. The Ansys Workbench environment is the glue that binds the simulation process. It tracks dependencies among the various types of data in the project. If something changes in an upstream cell, the project schematic shows that downstream cells need to be updated to reflect these changes.
Introduction to FEA
Before discussing Ansys software further, let us understand very briefly what FEA is and why it has gained prominence in recent times.
There are three broad methods to solve complex engineering problems: analytical methods, experimental methods and numerical methods. While analytical methods provide accurate solutions, they are limited to minimal geometries. Experimental methods can give accurate results, but they are costly, and in most cases not feasible financially. Finite element analysis (FEA), a numerical method to solve engineering problems, is a very versatile and comprehensive numerical technique that provides reliable engineering solutions. The most salient feature of FEA is the discretization of a given domain into a set of simple sub-domains called finite elements. The more the number of these finite elements, the more accurate the modelling and the subsequent analysis. The finite element method is a mathematical procedure based on solving differential equations as best as possible. A differential equation is any equation which contains derivatives, either ordinary or partial. They can be ordinary, partial or linear. From an engineering perspective, differential equations are important because they represent the language in which physical laws are expressed. The aim of FEA is to transform the differential equations of a system into a set of linear equations, which can then be solved by computer software.
Treatment of engineering problems basically contains three main parts: create a model, solve the problem and analyze the results. Ansys, like many other FEA programs, is also divided into three main parts namely the processors which are called pre-processor, solution processor and post-processor.
The Ansys pre-processor allows users to build geometry, define materials and generate element mesh. The Ansys processor allows users to solve problems by applying loads and obtaining solutions. The Ansys post-processor allows visualization and listing of results in a tabular form or as printouts.
Ansys offers a comprehensive software suite that spans the entire range of physics, providing access to virtually any field of engineering simulation that a design process requires. Organizations around the world trust Ansys to deliver the best value for their engineering simulation software investment.

As product complexity grows, so does the challenge of integrating individual components within a system to ensure they work together as expected.
Ansys is used wherever FEA is used, and use cases include structural analysis, industrial applications, tooling and automobile and aerospace engineering. Since it is a tool that focuses on FEA applications and has been doing so for the past many years, it is a very powerful tool with huge functionality. It is not an easy task to learn it on your own. There are a few credible Ansys training institutes in India; DesignTech CAD Academy is one of them.
