This document is a product capabilities matrix that compares the features of MSC Nastran, SimXpert, and Adams solvers. It shows that MSC Nastran can model various structural analysis capabilities including linear/nonlinear statics and dynamics, buckling, explicit dynamics. SimXpert offers focused solutions for structures, thermal, crash, and systems modeling capabilities. The MSC Nastran Desktop package provides the solver with Patran as a pre/post-processor, while other bundles add motion or structures modeling capabilities.
