Dear all,
I am simulating relativistic ions interaction in a calorimeter .
At a given point, my job gets into a never-ending loop
during which the following message is written and repeated
continuously in the myjob.err file:
------------------------------------------------
Stepop, dp/dx=<0!! ij, mmat, ekin, dpdx0 -2 30 7621.6471 -0.000335210437
*** Stepop: Trange < 0, Ij,Pla,Pthr -2 7632.81378 0.516069975
Kaskad: Dool<0!!, DOOL,IJ,PLA,PLAOLD,EKIN,TUSTEP,TVSTEP,MMAT
-1.67605039E-19 -2
7632.81378 7632.81378 7621.6471 5.E-16 5.E-16 30
0 GEODEN CALLED WITH AN ECONTR VALUE OF: -0.168E-18
ICALL = 131 IJ = 208 MREG,NEWREG = 48 48 IEST = 0
--------------------------------------------------
Can you explain it ? I guess that the problem concerns material n. 30
(C2H4 i.e. light polyetylene with density = 0.035 g/cm3)
but I don't understand why.
Maybe could it be related to a wrong mat.pemf card compilation ?
Many thanks for your help.
Cheers
Paolo
