Re: Strong discrepancy between update 31 and 32 while depleting with burnup steps and employing edepmode 3

Hi, you are correct that the code gives different results with versions 31 and 32. In version 31 the burnup step length was converted from MWd/kgHM to seconds based on energy deposition to only burnable materials which is not the same as the total power in energy deposition modes 2 and 3. In version...

Re: Looking for Serpent cross section directories

The thermal scattering data has not been taken from Serpent-v1.1.7 cross section data but instead from Serpent 2 "beta" cross section data that we used internally a while back. As I said in the previous post, I do not have specific information about the NJOY options used. You can of course create yo...

Re: Looking for Serpent cross section directories

If you are referring to the xs-data with the additional energy deposition data, I can provide the following information. Since the thermal scattering data did not need any modification for energy deposition calculations, I took the thermal scattering files from nowadays quite old beta cross section ...

Re: Compiling with MPI - runs not recognized

Regarding the MPI error I'm not sure if the -mpi command line parameter works properly. I would use mpirun (or similar) or srun if using SLURM. You can check Running parallel calculations section from here.

Re: "no KERMA data" but ACE file contains them

NJOY generates separate probability tables for the kerma coefficients and two different kerma coefficients are used by energy deposition modes 2 and 3. Since only one set of probability tables can be stored in the actual ace data, the other one is stored at the end of the file in PENDF format. Some ...

Re: ALL geometry in 3D

Did you try to follow the instructions Ana gave to you (i.e. try something yourself) and did you check the solid card definition from Serpent Wiki?
