Re: Lost particle with Multiphysics Interface

Hi!
Did you performed a ``checkMesh´´ command on your mesh?
Ciao

Re: Multi-physics interface

Hi Jesse,
no, I do not think that it is possible with the current interface (but I am not sure).
(I'm using an internally coupled Serpent/OpenFOAM).

Re: Multi-physics interface

Thanks Jesse! Anyway, to run multi-region simulations in OpenFOAM is not enough to have different cellZones or cellSets. You need to run a splitMeshRegions on your original mesh (or other equivalent command) in order to have the different regions separated in different meshes. You will end up with t...

Re: Multi-physics interface

I might be missing something but...
if you want to run a multi-region simulation in OpenFOAM (e.g., with chtMultiRegionFoam and co.),
you need to split the domain into separate meshes for each region, anyway.

Re: Multi-physics interface

Hi Vitor, In order to visualize the case with paraview or paraFoam, you need also the “boundary” file, which is not required by Serpent. Here is the boundary file for the MSR example: /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | Open...

Re: 2.1.16 Adjoint Weight Kinetic Parameters

Good, I am trying to compare Serpent results against experimental measurement from the Triga Mark II reactor of the University of Pavia. Jesse, did you use a fresh fuel composition or a “real” depleted one? Did you make also direct comparisons of Rossi's alpha measurements or something else? Thanks ...

Re: 'Outside' material within the geometry

Hi Phillip, the problem comes from the adoption of delta-tracking. In MCNP all the neutrons that enter in the "black rods" are lost. In Serpent, due to DT, many neutrons might enter and exit from the rod, if a virtual collision is not sampled there. You just need to add "set dt 0" at the end of your...

Re: Changes in group constant generation (version 2.1.13)

Hi, I am trying to generate XS for a discrete ordinates neutron transport code with sss2 (2.1.15). It seems to me that few-group scattering and scattering+production matrices (S1, S2, S3...) are produced only for INF_ and B1_ corrected spectra. Right? Is there a reason for that? Also, BETA_ZEROs are...

Re: serpent in SGE queuing system

Hi rullyh, I do not know your job scheduler, so my suggestion is probably useless. Anyway, I had the same problem on blue gene/q: it did not recognize the omp parallelization in each node. This is the final launching script which solved the problem. #!/bin/bash # @ job_type = bluegene # @ bg_connect...
