The Solver panel allows you to run an external program from within HyperMesh or assign and run a solver on selected analysis decks.
You can run linear static and Lanczos eigenvalue extraction solutions through a sparse matrix finite element solver. The solver is incorporated in Altair’s OptiStruct topology optimization software serving as the core solver for finite element solutions and is fully benchmarked using the standard MacNeil/Harding tests to ensure correct element formulation. For more information, refer to the OptiStruct online help.
