1.3 Advanced nonlinear Methods with Simcenter Nastran Sol401/402
In this advanced seminar, the possibilities offered by the Simcenter solutions Sol 401 Multi-Step Nonlinear and Sol 402 Multi-Step Nonlinear Kinematics are trained.
Theoretical approaches to solving complex non-linear tasks with the Simcenter Nastran solutions SOL 401 and SOL 402 are conveyed within the seminar and these are implemented using practical examples.
This includes detailed explanations of the contact algorithms, the time integration methods, the strategy parameters for generating a converging system and much more. The theoretical approaches will be deepened in the course of the training using selected practical examples.
In addition, there is the possibility of doing this course as a two-day transfer course if you already have experience with the Nastran solution 601.
