One of the most comprehensive and sophisticated analysis packages available, COSMOS/M offers
a tremendous range of analysis capabilities, including: 

Modeling, meshing and visualization of parts as well as assemblies. 
Comprehensive analysis capabilities: stress, frequency, displacement, buckling, heat transfer, nonlinear, dynamic response, fatigue, Computational Fluid Dynamics, electromagnetics, and high frequency analysis capabilities 
Design optimization 
COSMOS/M is a modular system that runs on Windows NT®, Windows® 95 and UNIX® platforms. 

The COSMOS/M BASIC System includes GEOSTAR, a CAD-like pre- and postprocessor, together with static, thermal and dynamic analysis capabilities. 

COSMOS/M Explorer, a special 5000-node version of COSMOS/M geared to the needs of consultants and users who are new to analysis, offers modeling, meshing, visualization, stress, frequency, displacement, buckling, heat transfer, nonlinear, dynamic response, fatigue, laminar fluid flow, electromagnetics, and design optimization at a remarkably reasonable price.
