Question regarding hex-y detector lattice

Dear colleagues; I have a simple question related to the hex-y lattices. I'm dealing with a 3D hex-y FA (VVER type) which has some positions with BP, as you can see in the following image: 30AV5-plot_geom1.png For that geometry I would like to get pin-by-pin results for an axial slice. I checked the...

Re: Hybrid MPI/Multithread runs with High memory requirements

Thanks for the data! BTW, I was just running with a simple msub script (example for the omp2.1 case): #MSUB -l nodes=50:ppn=20 EXE=/pathtosss/sss INP=/pathtoinp/inp # load module in cluster module load mpi/openmpi/2.1 # Calculating number of threads per core: export OMP_NUM_THREADS=$((${MOAB_PROCCOU...

Re: Output in IFC type 2

That could probably work I suppose (I'll check it). Nevertheless I changed the approach and I directly get the power with a detector (dr -8) with the same discretization as IFC. Maybe it could be a good feature for users to have this option as option in IFC to maintain all the coupling capabilities ...

Re: Output in IFC type 2

Hi Ville, Actually I am dealing with a PWR FA case where the spacer grids are supposed to be modeled explicitly, thus I have a FR pin lattice with some axial dependence (basically the same pin is inside a Zr box in the grid spacer zone). The problem is that if I dilute the spacer I lose the dependen...

Output in IFC type 2

Dear colleagues; I'm dealing with an IFC file type 2, where I'm trying to get a Power output into a file for further coupling. When analyzing the files I was surprised by the size and I realized that the output was full of zeros in duplicated positions. I simplified the problem and It looks like the...

Re: Issues with coupled-transients calculations

Jaakko, When I include this, I get lots of lines for each MPI node such as: Mon May 28 16:14:31 2018[1,0]<stdout>:1001.03s 2 1.030530E-07 9.786520E-08 1.003766E+00 5.720000E+02 9.000000E+00 Mon May 28 16:14:31 2018[1,0]<stdout>:1001.03s 2 1.030530E-07 1.219852E-07 1.003766E+00 5.720000E+02 9.000000E...

Re: Issues with coupled-transients calculations

Hi Ville! I replaced the CheckValue-statement at line 253 of dopmicroxs.c, but now the problem arises afterwards (compiling with icc17 + OMP 2.1 in debug mode): First I get a warning message like this: ***** Tue May 22 11:17:06 2018 (seed = 3, MPI task = 16) Warning message from function SampleReact...

Re: Issues with coupled-transients calculations

Hi Ville! I think that I could (probably) give some hint on the memory problem for Hybrid MPI-OpenMP calculations. I compiled in debug mode for several combinations (gcc 4.7 and 7 / icc 17 + OMP 1.8/2.1) and I always get the following error for some MPI slaves at the beginning of calculation: - MPI ...

Re: Detectors in transient simulations

Thanks! With the correction it works properly.
Best,
