Ciao Francesco,
indeed it appears you have a shell of vacuum around your simulation, which would correspond to a 0 in an hypothetical “ascii_file.dat”.
I would say the effect is more aesthetically than physically disturbing. Clearly it might affect very slightly your results (as a matter of fact you might add a lice of vacuum to your simulation instead of air).
I don’t have your simulation files to check but I guess you might have to look in the algorithm generating the voxel file.
Best,
Vittorio

In detail, in every plot i did, there is a parallelepiped cage sourrounding the phantom. I think this cage corrispond to region VOXEL in the geometry, and fluka manual (page 298) says that this region VOXEL is a sort of cage for all the voxels of the model. According to the manual I assigned to this region the material vacuum. I also assigned air and other materials to the phantom but everytime i do the plots i see this cage contour around the phantom.
