Dear Fluka-team,
I just ran into a little problem:
I've set up an input file and varied the target material (proton beam with 600 MeV, main interest RESNUCLEI for spallation and neutron capture products). All works fine for 10 different materials (UC2, Ta, Pb, Sn, Nb ...) but it keeps crashing with Th-232. The only things I change in my input are those 3 lines according to thorium with SDUM 232-TH and ThO2 (see below). The run starts normal and crashes after several hundred thousand particles with "Floating Exception".
As the other 10 almost identical inputs run successfully with 7.5E6 particles I would exclude some big bug in my input. So, I either made something wrong with the material composition (and then I couldn't understand why several hundred thousand particles are okay), or it is something with the system configuration (Fedora Core, gcc 3.2.3) or something special to thorium...?!
Best regard & thanks a lot,
Rene
