        LS-DYNA is the world's most well-known general-purpose nonlinear finite element software capable of simulating complex real-world problems. It is suitable for studying physical phenomena involving large deformations, complex material models and contacts in a variety of 2D and 3D nonlinear structural dynamics problems. LS-DYNA can switch between explicit analysis and implicit analysis with different time steps. Different disciplines such as thermal coupling analysis, computational fluid dynamics (CFD), fluid-structure interaction, smooth particle fluid dynamics (SPH), meshless Galerkin (EFG), particle method (CPM), boundary element method (BEM), etc., can be combined with structural dynamics for analysis. ANSYS/LST (Livermore Software Technology) aims to provide users with a seamless way to solve problems such as "multi-physics" and "multi-scale" through "multi-process", "multi-stage", and LS-DYNA.
