Hi all,

I have also found something strange using scoring mesh. I was performing similar tests to check consistency of results: Cube of water 50x50x50 cm3. Cubic scoring mesh with number of voxels running from 1x1x1 to 20x20x20. For each configuration of the mesh I launch 100 electrons of 6MeV at the center of the cube and I get the following deposited energy, integrated over the whole mesh:

nvoxels = 1x1x1 = 1 --> edep = 592.5 MeV --> edep/nvoxels = 592.25 MeV.

nvoxels = 4x4x4 = 64 --> edep = 38.18 GeV --> edep/nvoxels = 596.57 MeV.

nvoxels = 5x5x5 = 125 --> edep = 74.7 GeV --> edep/nvoxels = 597.66 MeV.

nvoxels = 20x20x20 = 8000 --> edep = 4767 GeV --> edep/nvoxels = 595.90 MeV.

In the macro I use I change just the mesh banning from run to run. What could be the problem?

Thanks!
