Advanced Training SOL401 and SOL402

Introduction to the new Simcenter Nastran Advanced Nonlinear Solution Sequences SOL401 and SOL402


Want to master Advanced Nonlinear Analysis using Nastran SOL401 and SOL402? Join us in this Advanced Training to successfully start or switch from other nonlinear codes!

The training will guide you through the fundamentals of nonlinear analysis. The nonlinear analysis setup procedure is demonstrated using practical examples. Results and performance of SOL401 and SOL402 are compared to other Nastran solution sequences such as SOL106, SOL129 and SOL601.
