COSMOSWorks is a commercial implementation of FEA, capable of solving
problems commonly found in design engineering, such as the analysis of
deformations, stresses, natural frequencies, buckling, heat flow, etc.

It belongs to the family of engineering analysis software products developed by the Structural Research & Analysis Corporation (SRAC). SRAC was established
in 1982 and since its inception has contributed to innovations that have had a
significant impact on the evolution of FEA. In 1995 SRAC partnered with the
SolidWorks Corporation and created COSMOSWorks, one of the first
SolidWorks Gold Products, which became the top-selling analysis solution for
SolidWorks Corporation.

The commercial success of COSMOSWorks integrated with SolidWorks CAD software resulted in the acquisition of SRAC in 2001 by Dassault Systemes, parent of SolidWorks Corporation. In 2003, SRAC operations merged with SolidWorks Corporation.

COSMOSWorks is tightly integrated with SolidWorks CAD software and
uses SolidWorks for creating and editing model geometry. SolidWorks is a
solid, parametric, feature-driven CAD system.

As opposed to many other CAD systems that were originally developed in a UNIX environment and only later ported to Windows, SolidWorks software was developed specifically for the Windows Operating System.

In summary, although the history of the family of COSMOS FEA products
dates back to 1982, COSMOSWorks has been specifically developed for
Windows and takes full advantage this allows for a deep integration between
SolidWorks and Windows.

Finite Element Analysis, commonly called FEA, is a method of numerical

analysis. FEA is used for solving problems in many engineering disciplines

such as machine design, acoustics,electromagnetism, soil mechanics, fluid

dynamics, and many others.

In mathematical terms,FEA is a numerical technique used for solving field problems described by a set of partial differential equations.

In mechanical engineering, FEA is widely used for solving structural,
vibration, and thermal problems. However, FEA is not the only available tool
of numerical analysis. Other numerical methods include the Finite Difference
Method, the Boundary Element Method, and the Finite Volumes Method to
mention just a few.

However, due to its versatility and high numerical efficiency, FEA has come to dominate the engineering analysis software market, while other methods have been relegated to niche applications. When implemented into modern commercial software, both FEA theory and numerical problem formulation become completely transparent to users.
