Duration: 3 Days


In this advanced seminar the handling of the NX module Advanced Nonlinear FE Analysis is trained. Within this seminar the theoretical approaches to solve complex nonlinear problems with the NX Nastran solutions SOL 401 and 402 will be teached and shown based on practical examples. This includes detailed explanations of the contact algorithms, the time integration methods and the strategy parameters to generate a converging system, etc. The theoretical approaches are deepened during the training with selected practical examples. Finally there is a comprehensive list of collected tips and techniques for non-linear analyzes.
