The design and development of a space station require a multidisciplinary analysis system to enable the use of a common geometric model definition to analyze the thermal, structural, and flight mechanics of the space station to achieve a high level integration of the various analyses.

In response to these requirements, the IDEAS² software was created by integrating SDRC®'s I-DEAS® software package with a set of NASA codes also known as IDEAS®. The NASA codes supply the spacecraft-specific capabilities for orbital lifetime prediction, control dynamics simulation, and plume impingement analysis. The I-DEAS® software provides the solid modeler, relational database, finite element pre/post processor, and structural analysis. Open architecture of I-DEAS® provides utilities which allow the developers to integrate their own software functions in a very seamless way such that both standard and specialized capabilites are in the same integrated package.
