1.1 Training Basic Structural Simulation with Simcenter Nastran Sol101,103,105,106,153

For structure simulations in NX / Simcenter 3D, model preparation, model construction and result evaluation are carried out in the pre / post environment (formerly Advanced Simulation) and NX Nastran is used as a standard solver.
The examples and learning content of this training essentially deal with the FE methods of linear statics, i.e. the Nastran solution SOL 101, which also includes the analysis of assemblies and contacts. Free vibrations (modal analysis) with the SOL 103 solution and temperature analyzes with the SOL 153 / SOL 159 solutions are also explained. Non-linear structural analyzes are processed using the SOL 106 solution, but more complex non-linearities should be calculated in the SOL 601 / SOL 701 solution or with SOL 401, SOL 402 - covered in the advanced seminar "Advanced Nonlinear Methods".

If the participant wishes, the interfaces to other solvers (e.g. Ansys, Abaqus, LS-Dyna) can also be viewed.

The participants of this seminar will be able to build FE models from complex geometry, to simulate them and to evaluate the results.

The optional fourth day can be used to work on specific use cases of the participants and to understand the contents of the training.
