How to fix geometry errors

There can be basically two errors and two possible complications.

  • Hole in the geometry surface mesh - Can be fixed by manually creating triangles one by one or closing it at once with "Geometry->Edit Faces->Close hole"
  • Intersected triangles - Discover with "Geometry->Edit Faces->Find Intersected Triangles" and fix with "Geometry->Edit Faces->Break Intersected Triangles"

  • Very small distance between nodes (near nodes) - Can be fixed with "Geometry->Edit Nodes->Merge Near Nodes"
  • Too small or too slim triangles - Can be fixed with "Geometry->Edit Faces->Collapse Face Elements"
