Hello,

This is strange. Even if you cannot provide your mesh, running under a debug build to obtain the exact line where the crash occurs, and indicating the minimum/maximum x,y,z values might help.

Hello, If you have a porous zone, the elliptic blending model might not be the best solution after all. What you probably want is to use turbulence source/sink terms to reduce / adapt the turbulence (at least the k or Rij terms) in the porous zone. We usually leave turbulence "as is" in po...

Hello, no, the turbulent model is global. One solution would be to couple 2 instances of the code, one for each zone (but this is complex and requires extra precautions). I'm not a turbulence specialist, but using LES for example, you should naturally have the correct type of behavior in different z...

Hello, This is surprising. When you run with 0 or a small translation, are all mesh quantities (volume, ...) identical ? Could you run in a debug build, to determine the lines where thins fail when computing mesh quantities ? What are the x,y,z bounds of your initial mesh ? I also recommend upgradin...

Hello,

You need to add ''--nprocs <number_of_mpi_ranks>" to the run command inside the runcase.

Check "code_saturne run --help" for the exact syntax (there is a short an long variant)

Hello,

The documentation might not be completely up to date in this regard.

For anisotropic porosity, the xy term is one of the terms which appears when the porosity tensor is not alligned with the axes and you apply a rotation to describe it in the reference coordinates.

Hello, There was a recent question about this on the forum, so searching recent posts with "parallel" should help you find it, and all the associated answers. Things have changed slightly since v3, but "code_saturne run" options in the runcase are available for this. Regards, Yvan

Hello, Here again, you probably need the python-dev package (installing "-dev" packages in general for needed packages is recommended in the install doc, as it is a frequent issue). Another option is to add the --disable-python to the MED configure options (re-running the configure of MED,...

Hello,

Yes, SALOME's favored format is MED. Importing CGNS from SALOME is OK, but for export and use by Code_Saturne, MED is recommended.

Hello, Is your group named "Group 28", or simply 28. If you have whitespace in your group names, you need to protect that whitespace inside the name. This can be done by addding a '\' (but the C compiler "eats" one, so you need 2 in C, I'm not sure in Fortran, or mixing quotes: &...
