Re: A logic code error (possibly?)

Hi Joseph,

are you sure you are using the latest version of FLUKA, I've made the
same plot and I got the attached figure.
However you have be careful that the plots of the geometry is not a
proof that the geometry is ok. For example overlapping regions will not
show up correctly.
