    Dear FLUKA authors:

    I would like to make sure that I am producing optimum FLUKA geometries. =
    Where I define optimum as the fastest tracking possible regardless of =
    the time required for initialization.

    1) Is it better to define regions with non-overlapping =
    zones(sub-regions), or should one use the fewest number of zones to =
    define a region?

    2) If I have the same number of zones for overlapping and =
    non-overlapping, but for overlapping I can use fewer bodies to define =
    the zones, which is better? Does fewer parameters(bodies) produce =
    faster tracking than non-overlapping zones?

    If the answer to producing fast tracking depends on other things can you =
    tell me what that might be?=20

    For the purpose of this mail assume I am using only the recommended =
    FLUKA body types (RPP, SPH and infinite bodies)

    Thanks
    Kerry
