CATIA stands Computer Aided Three-dimensional Interactive Application. Developed By The French Company Dassault Systèmes in 1997. It is A Multi-platform Software Suite designed For Computer aided Design (CAD), Initially it was developed for designing the Dassault Mirage fighter jet. Over the years it was used much more for Computer aided Engineering (CAE), Computer aided Manufacturing (CAM), PLM And 3D


Ansys Software was founded in 1970 by John Swanson. It is used to design products and Semiconductors, basically every engineering simulation needs Ansys Design process. That simulation test product durability, Fluid Movements, Temperature Distribution and Electromagnetic Properties and also you can import geometries of complex assemblies . Compared to CAE tools, Ansys software delivers better result.
