If the input CAD body contains an overlapping face, SimLab will try to resolve the intersection by default during surface meshing. Sometimes, resolving the intersections automatically creates a bad mesh and the geometry is collapsed. Bringing it back to the original shape takes time.
To skip the automatic resolving of an intersection within a body, use the environment variable:
SIMLAB_SKIP_INTERSECTION_REMOVAL=1
To add the above environment variable:
- Navigate to File > Preferences > Application > General.
- Click the User defined environment variables button.
- Under the Name column, enter SIMLAB_SKIP_INTERSECTION_REMOVAL.
- Under the Value column, enter 1.
- Click OK.

Example
In the below example, the CAD body contains overlapping elements. By using the environment variable, the automatic resolving of element intersection can be skipped.
#1: Surface Mesh (with NO environment variable)

#2: Surface Mesh (with environment variable)
The SIMLAB_SKIP_INTERSECTION_REMOVAL environment is set as described above.
