GEO-DEBUG (as well as the FLUKA debugger) can flag illegal geometries, that is:
- geometries with points belonging to more than one region
- geometries with point not belonging to any region
They cannot find EMPTY regions (regions containing no points). If body A is
smaller than body B (for instance they are both RPP and A is completely inside
B) a region
A - B
is empty (there are no points inside it) but the region definition is legal.
