[Gate-users] cylindrical volume crash

Dear Gene,
The problem might be that, while using this example the way it is written,
without defining your 'world' geometry, may result that a part of your
geometry is outside the world, if by default the predefined world shape is
50x50x50 cm3. (since Rmax of your CPET is 60cm).
I would suggest to start by:
/gate/world/geometry/setXLength 200. cm
/gate/world/geometry/setYLength 200. cm
/gate/world/geometry/setZLength 200. cm
followed by the CPET example commands.
Sorry I can't access Gate at the moment on my personal computer to check it,
but I think it's worth a try.
Please tell me if it works.
Regards,
Rony.
