Dear Fluka users and authors,
I have met a problem in the simulation of secondaries of underground muons. The
muons were inputted by option Source from a data file which is generated by GEANT3
simulation from top of mountain to underground. In SOURCE routine, just
momentum, direction cosines and positions
of muons are read (PBEAM,UBEAM,VBEAM,WBEAM,XBEAM,YBEAM,ZBEAM). When WHAT(1) of
START in input file is 10, running is normal. When it is more than 20 the
running stops. The .err and .out show "Stepop, dp/dx=<0!! ij, z, a, mmat,
ekin, pthrmx, dpdx0 11 -1 0 33 415.763068
Abort called from STEPOP reason dp/dx=<0 Run stopped!
This problem has stopped me about three weeks and I still have not any ways to
save it now.
Could you tell me the possible bug or how to check it?
Thanks and Best regards!
