The MacNeal-Schwendler Corporation (MSC) has provided sophisticated computer-aided engineering (CAE) software to its clients since 1963. MSC/DYTRAN is a three-dimensional analysis code for analyzing the dynamic, nonlinear behavior of solid components, structures, and fluids. It uses explicit time integration and incorporates features that simulate a wide range of material and geometric nonlinearity. It is particularly suitable for analyzing short, transient dynamic events that involve large deformations, a high degree of nonlinearity, and interactions between fluids and structures.
