Dear all,

In addition to previous messages from Mina and Chris, volume calculation
could still remain a problem:
- for FLUKA/FLAIR users with Linux OS, SimpleGeo works very well with
Windows under the VirtualBox software, without any difficulty. The
geometry file could be imported between both OS through shared folders
- once before with a complex geometry (concentric spheres and tori),
MCNP was unable to assess the region volume for an energy deposition
tally. So I had to calculate every region volume...

The method described by Anna (from Alberto) seems to be neat.
