Warning: Debug mode mesh, nothing will be done

Warning: tetgen.exe : !! Found 10519 pairs of faces are intersecting.

It means that the 3D model is made with intersecting facing, which can not be run in I-Simpa with SPPS.
Possible solutions:

• correct/simplify the 3D model
• export to another format (PLY)
• change the 3D CAD software (freeCAD for example)
