PERMAS Integration

PERMAS is a powerful FEM-Solver from INTES for solving complexe simulation tasks. With PERMAS you can solve statics, dynamics, temperature fields, fluid-structural coupling and nonlinear analyses. 

We offer a PERMAS interface which is integrated in NX Advanced Simulation and extends the selection of the Multi Solver Support.
