I have a detector which is a quare around the square beam hole.
Inside it, there arelots of tungsten(36) and scintillator(42)
plates hold in a iron shell.
I used a series of infinite half space or planes to define
them as in the attached det1a.inp and det1b.inp. Then I
substract all the volumes(W and scint plates) in the world
definition. But Fluka won't run on the card. The program will
be aborted. If I only use five volumes
or less, then it works.
The difference between det1a.inp and det1b.inp is just that
det1a.inp has less bodies defined.
The same problem happened when I was defining the other
detector as in det2.inp where there are just BOXs, ARBs, and
no infinite planes. The only difference is that the number
limit for different bodies went up to 10.
It seems to me that it's not possible to substract
more than a certain number of boolean operation of different
bodies although it works with any numbers of single bodies.
Is this true? Can I get around this to define this kind of
Thanks a lot. Sorry if the input cards are too messy.
