Prolematic parallel calculation on certain workstations

Hi! Recently I am trying to use SERPENT 2.1.30 on some of my workstations. The problem is that when the number of threads using OpenMP exceeds the number of core (I have already turned on the hyper-thread in bios), the memory usage increases drastically with ongoing depletion steps and the program s...

Re: Temperature feedback in Serpent 2

It is nice to know that the calculations are straightforward. The current temperature feedback model will be somewhat replaced by the FINIX fuel behavior module (see http://montecarlo.vtt.fi/mtg/2013_Berkeley/Ville_Valtavirta2.pdf ) developed in-house by T. Ikonen. FINIX will also enable depletion ...

Re: New mesh plotter capabilities

Yes, that's right, the limits are set to geometry min and max by default. The mesh plotter works best in 2D geometries. In 3D the distributions are flattened, which sometimes makes interpreting the plots a bit more complicated. Hello Jaakko, today I tried serpent 2.1.23 with these mesh plotters and...

Re: Memory allocation failed

Hello, I have the similar issue here: my serpent2.1.19 is running on my PC with 8 cores and 16GB memories on Ubuntu 14.04. Recently I am doing the burnup parallel omp calculation for MSRs and have to deal with a lot of nuclides. So during the calculation, the following error messages come out: Input...

Re: HOWTO: Installing Serpent on Windows via Cygwin

Are you running with MPI? The first error looks like it's been printed by two separate tasks. This happens if you running Serpent with mpirun (or similar), and the code is not compiled with the MPI options. Instead of starting one parallel calculation, mpirun starts several independent runs. No, I ...

Re: HOWTO: Installing Serpent on Windows via Cygwin

Hello Tomasz, thanks for your instruction! Today I have tried your method for serpent 2.1.19. During the make process there are a lot of warmings but they didn't interupt the installation. After the installation, the version information can be displayed correctly, the exe in cygwin x64 (on win 7 x64...

Re: Lattice power output

Hello,

I have this question on the power distribution. Since for a PWR e.g. we normally set a lattice for an assembly and a lattice for the whole core. So if the <lat> is set as the lattice for an assembly, which assembly in the core is taken for the calculation?

Thanks.

Re: New mesh plotter capabilities

Hello,

is that possible to provide an output or some quantitative explanations for these plots? I mean these plots are beautiful, but without legend or the detailed data, these plots can only be used as show, but not something can be used for interpolation of some issues.

Thank you very much:)

Re: lat maximum limit

Try changing MAX_LATTICE_ITEMS on line 134 of header.h. Notice that this is a header file used by several subroutines, so you need to recompile the entire source code (make clean, then make). Thanks for your answer. But after the modification of that line from 100*100 to 200*200 and new make, the e...

lat maximum limit

Hello *, in my model there are more than 15000 fuel tubes just hexgonal placed there in the reactor and I have written an array in lat, and run the input file with serpent 1.1.19 and 2.1.19. But 2.1.19 will be terminated by a error message that lat has a limit of 10007, and mine has too many. I woul...
