Dear Jeremy,

In order that BXDRAW is called for electrons, positrons or photons, any USRBDX card must be present in the input file (USRBDX sets some internal flag which activates boundary crossing scorings). Note, that in the next FLUKA release, this will not be anymore necessary.

(thanks to Alfredo for clarifying this issue)

Cheers, Anton

Subject: Problem with MGDRAW

Dear FLUKA users,

I am having trouble with the boundary crossing entry of MGDRAW. For some reason, it looks like MGDRAW is not being called for electrons or photons. I have generated an input and mgdraw.f file (attached) that illustrates this problem. When I set the beam particle to PROTON, NEUTRON, or 4-HELIUM, for example, everything seems to be working just fine and a USERDUMP file is created with the requested information. When I change the beam particle to PHOTON or ELECTRON, however, the USERDUMP file is not even created.

I have tried switching between PRECISIO and EM-CASCA defaults but that does not seem to change anything. Any help would be appreciated.

Thanks,
Jeremy
