MSC Dytran is a general purpose, three dimensional explicit finite element analysis (FEA) software program for simulating and analyzing extreme, short-duration events involving the deformation of structural materials and the interaction of fluids and structures. MSC Dytran provides a comprehensive and robust solution to simulate multi-material impact, crush, penetration, explosion and other fluid-structure interaction (FSI) applications. A broad range of material models and element types enable users in many industries to perform VPD experiments and "what-if" analyese on design concepts before building and testing costly physical prototypes.
