Removing Problematic Faces

If you want to change the Validation Mesh e. g. by adding Mesh Controls or Virtual Topology, and cannot remesh the geometry, there might be so called "Problematic Faces" in your Model. This task shows how to find and remove such faces.

  1. Close the Mechanical Application, go to the Project Schematic and open the Model cell of the Finite Element Modeler.

  2. Check the Tree Outline for Problematic Faces:

    • If there are no Problematic Faces, you can skip the following steps. Add mesh controls like a lower element size Mesh Controls > Sizing to make meshing possible.
    • If there are any Problematic Faces, select Skin Detection Tool (SDT) in the Tree Outline. In the Details View, switch Forbid Closed components to Yes:



  3. To create geometry with the changed settings, right-click Initial Geometry > Generate.

  4. If Problematic Faces still exist, it is additionally necessary to reduce the Cut Angle or the Tolerance Angle in the SDT Details View. After changing these angles, the geometry has to regenerated again (Initial Geometry > Generate).

  5. Close Finite Element Modeler after dissolving the Problematic Faces. Right-click on Model cell of the FE Modeler and choose Update:

  6. Double-click on Model cell of the TOSCA Validation Analysis System. When asked whether to read the upstream data or not, choose Yes, if you generated new Geometry in the FE Modeler, otherwise click No.

    After these steps remeshing is possible and the Validation can be continued.
