OptiStruct

Simcenter OptiStruct is a high-end finite element analysis (FEA), multiphysics simulation, and design optimization software used to evaluate and improve structures under static, dynamic, thermal, acoustic, fatigue, crash, impact, and other complex loading conditions. Its main strengths are its “One Model, One Solver” approach, linear and nonlinear analysis, advanced topology and shape optimization, composite and nonlinear material analysis, fluid-structure and thermomechanical coupling, and highly nonlinear explicit simulations such as crash and drop testing. The software is designed for professional engineering workflows and integrates with other Simcenter products, third-party tools, and user-developed code through its open architecture. Performance is a major advantage, particularly for large models with millions of degrees of freedom, while specialized solvers such as FASTFR and AMSES are designed to accelerate frequency-response and eigenvalue calculations. Its capabilities and breadth make it highly efficient for complex engineering studies, although the extensive functionality means that inexperienced users can face a significant learning curve. Siemens provides technical resources and complementary tools such as Simcenter HyperMesh and HyperView.
