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.

This module contains the main ANSYS Software with several ANSYS products
(i.e Fluent, EM, RSM, CFX, Mechanical APDL, etc.).
