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

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...

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...

Can you send me the input file?

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

Serpent supports mesh-based geometries in OpenFOAM mesh format and CAD geometries in STL. See: http://serpent.vtt.fi/mediawiki/index.p ... inition.29

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...

Yes, I'll include it in the next release.

Try adding: after lin2 791 of tracking.c.

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...
