Bug in source type "disk"

[bernhardkaplan]

When using the source type "disk" the launched photon density has a dip in the center of the circle and along the radial axis.

The output has been generated using this json parameter file

The volume file is:
{ "Shapes": [ {"Name": "cubic300"}, {"Origin": [0,0,0]}, {"Grid": {"Tag":1, "Size":[300,300,60]}} ] }
and the run command:
mcx -A -f 8benchmark-disk_modified.json -r 100 -b 1 8benchmark-disk_modified "$@"

Python plot script is here

close, no longer reproducible. if the issue remains under certain conditions, feel free to reopen.

possibly this was also caused by the low precision Windows rand() function, see Issue #31 and the fix.
