LS-DYNA is a general purpose, explicit finite element program used to analyze the nonlinear dynamic response of three-dimensional structures. LS-DYNA's comprehensive selection of material models, element formulations, and contact algorithms have enabled users worldwide to successfully solve many complex automotive safety, metal forming, structural, and failure analysis problems. LS-DYNA incorporates a number of advanced features including fully automated contact handling and error-checking, Hybrid III dummy model, thermal modeling, adaptive meshing, coupled structure/fluid modeling, bi-material elements, multiple airbag inflator models, integrated 2D and 3D modeling, and multiple local coordinate systems. LS-DYNA is directly supported by a wide variety of 3rd party pre- and post-processing systems.
