Model Simulation#

Description#

As part of the Z-set package there is a model simulation mode, which can be applied to any differential model as supplied by the user, or used to simulate material behavior for a volume element based on one of the standard behaviors, or a ZebFront behavior (see the developers handbook for a description of the latter). To allow rapid prototyping of models, ZebFront modes are available in either a pure model definition, or (with small additions) to user behaviors defined in this manner.

For mechanical material behaviors, some special functionality is provided. This includes generalized mixed-mode loading, and the visualization of yield surfaces. Note that curve output of a finite element calculation may be obtained using the **curve command (in Zebulon), and then fed into the simulator for loading to obtain more detailed output or yield surface visualization.

Syntax#

% Zrun -S problem  \(\hookleftarrow\)

More Information#

For more information on simulations, please refer to the following manual sections, and example files.

  • Tests in the directory $Z7PATH/test/Simulator_test where there are many examples of input files exercising all the simulator options.

  • Examples handbook and corresponding example files. There is some information showing basic use (the Simulation chapter), and many more examples in the Material Behaviors chapter. In fact, most of the behavior outputs are generated with the simulation module.

  • Developer handbook to see how to make simulation compatible models including ZebFront.
