Re: Zero-Kelvin XS data

We have some test libraries with 0K data. I'll send you a link by email.

Re: Fixed Source Fuel Depletion calculation

Forgot to mention that you also need to have "set bala 1" for this to work. Also, when you are running fixed source calculations with a cell source, it's good practice to put a bounding box around your source cell using sx, sy and sz. This will limit the region where source points are sampled, so th...

Re: Fixed Source Fuel Depletion calculation

The problem is related to the way secondary particles are stored in OpenMP parallel mode. Try commenting out the two if-sentences on line 37-38 of toque.c: if ((lim = (long)RDB[DATA_COMMON_QUE_LIM]) > 0) if ((long)RDB[ptr + PARTICLE_MULTIPLICITY] > lim - 1) The "set bala" option is related to the sa...

Re: Fixed Source Fuel Depletion calculation

If you are using version 2.1.31, try "set bala 1" and let me know if it helps.

Re: Fatal error with serpent 2.1.31 and mdep

It seems that the problem is that you are switching group constant generation off with "set gcu -1". This disables some processing routines needed for micro-depletion. I did not consider this option when implementing the feature. I'll add a check that group constant generation is on when the mdep ca...

Re: Warning using Response Matrix acceleration

Try adding:

Code: Select all

               if ((long)RDB[DATA_RMX_CONVG_ACC] == YES)
                    ScoreRMXCurr(part, x, y, z, E, wgt, id);
after lin2 791 of tracking.c.

Re: 2.1.30 and JEFF3.3 Nuclear Data

OK, so here's a fix that worked for my test calculation... Add: /* Reset count */ nfp = 0; /* Add nuclides from ACE data */ ace = (long)RDB[DATA_PTR_ACE0]; while (ace > VALID_PTR) { /* Get ZAI */ ZAI = (long)ACE[ace + ACE_ZAI]; /* Separate Z and A for check */ Z = (long)((double)ZAI/10000.0); A = (l...
