About Validation Run in Tosca ANSA® environment

In Tosca ANSA® environment, once RUN_SMOOTH command finishes, the elements of the input model are replaced with the smooth isosurface representing the optimization result (with the exception of loaded elements that remain unchanged). At this point, the model can be saved in the format of the desired solver using File > Output > <solver name> menu command. However, this model will only contain the geometry information, namely the smooth isosurface (or model surface) generated by Tosca Structure.smooth plus the loaded elements copied from the original model.

In order to construct an optimized model suitable for the validation run, following actions are provided by Tosca ANSA® environment:

  • BATCH_RECONSTRUCT or MANUAL_RECONSTRUCT: modification of the surface
  • SOLID_MESH: remeshing of the volume defined by the modified surface
  • VALIDATION_OUTPUT or MODIFICATION_FILES: saving the remeshed model and the information copied from the original model in solver format.

If needed, FE analysis of the produced model by the selected solver can be started from within Tosca ANSA® environment using VALIDATION_RUN. This option is available only when the verification model was created using the VALIDATION_OUTPUT command. Due to specific aspects of ANSYS® models not supported by ANSA, in this case the generation of validation models using modification files is required. The validation run can then be started manually in your familiar solver environment (ANSYS® Workbench). This is also an alternative if the standard way using VALIDATION_OUTPUT does not work.
