    ... about modelling more complex systems: we routinely run systems
    with tens of thousands regions, modelling km's of accelerators with no
    problems. There is no limitation in the FLUKA geometry (apart a limit
    of 20000 different "prototype" regions before repetitions, with
    repetitions they can be millions). Again, if you have problems it is
    almost certain you made a mistake in defining your geometry. Removing one
    or more regions and getting it (apparently) to work, doesn't prove at
    all it was (and it is after removal) correct. Only running the geometry
    debugger can help, please run it.
