Some time ago I found an issue in G4NeutronHPFissionData.cc which resulted in the code (having the 232Th isotope inside the materials) crashing if used with $G4NEUTRONHP_SKIP_MISSING_ISOTOPES set to 1, (for geant4.9.3 onwards) because it stopped using the fission cross-section of 232U for 232Th (which in reality does not undergo fission). Please see bug report:
The bug was kindly fixed by Tatsumi Koi, by adding a safety check line to G4NeutronHPFissionData.cc, which is:
if ( ( ( *theCrossSections )( index ) )->GetVectorLength() == 0 ) return result;
Now that I have to use the G4FissLib model for fission, I ran into the same problem, and I don't know how to modify G4FissLib.cc in order to correct this.
I would be very grateful if you could please suggest a fix for G4FissLib.
Thank you very much,
