This seminar aims to empower the user to convert a geometry model in a computational model. This conversion can be done both with individual parts or assemblies. NX automatically generates the following three files in an associative assembly structure (pre-processor):
• The parts simplification can be made in the "idealized file". This keeps the original structure intact.
• In the "FEM file" the meshes and material assignment are performed.
• In the "simulation file" the constraints and loads are defined.
The calculation is performed with NX Nastran. The results of evaluation are done in a separate navigator who is also called Post-Processor. This assessment will be explained in detail during the seminar. So many comparisons can be performed in a presentation mode. All results can also be shown in animated GIF format.
NX offers per default NX Nastran solver. Other calculations can be done with the following Solvers (also integrated into NX):
• ANSYS
• ABAQUS
• MSC Nastran
• IDEAS UNV
• More Solver request at Siemens
Since the handling of pre- and post-processor is always the same, customers who use other solvers can participate in this seminar.
"All theory is gray," said Goethe. The plausibility of the results is illustrated with numerous examples.
The use of stand-alone solutions with the above solvers brings the disadvantage that the interfaces are not associative with the basic models. Therefore, this integrated NX solution adds the ability to have full access to the parameters of the models. Moreover model changes can be considered much easier to update.
Through the "Optimization Setup", NX can access all model parameters. The optimization is performed with the solver AltairHyperOpt. The results are presented in an Excel spreadsheet. The optimization process involves the following steps:
• Define target direction (minimize, maximize, target value)
• Define boundary conditions (Stress, Deformation)
• Define variables (Sketch parameters, Feature param.)
• Number of iterations pretend
• Perform optimization
