Description Federico.Carminati 2020-04-04 21:51:06 CEST 
The use of the option “G4NEUTRONHP_PRODUCE_FISSION_FRAGMENTS” requires the presence of the files in

G4NDL4.6/Fission/FF

if one is using an alternative DB, such as those in

https://www-nds.iaea.org/geant4/

the instructions do not mention to copy this directory from the standard GEANT4 neutron files. The code looks for the data, and if these are not found, it fails silently, but then the application crashes because the fission fragment MAP is not filled.

The instructions should be updated and the code protected.

Also, it should be checked whether this option and G4NEUTRON_HP_USE_WENDT_FISSION_MODEL=1 are active at the same time, since these are mutually exclusive.

Regards, Federico Carminati

Hi Federico,

   I'll look into the conflicting environment variables.

However, I'm a bit confused about the directory copying problem.

Isn't that covered in https://www-nds.iaea.org/geant4/

in step 2 under "Installation of the new neutron data libraries" ?
