Re: Source term in momentum equation - GUI bug - "rho" not declared in this scope

Hello,

I just fixed the issue in master, v8.2, and v8.0 branches, and synced the GitHub repo.

Best regards,

Re: Clipping of the Reynolds-stress tensor

Hello, Are you using v8.0, v8.2, or the master branch ? The time-stepping priority you describe does sound like a bug, unreported/noticed so far, so we'll need to check that. Regarding the clippings, Jean-François just pushed a change allowing separate deactivation of clippings for Rij and epsilon, ...

Re: Clipping of the Reynolds-stress tensor

Hello,

I am not sure about details, but talked about it a bit with my colleague, and he expects to push a fix within a few days. I am not sure how much influence this can have on the computation.

Best regards,

Re: Clipping of the Reynolds-stress tensor

Hello,

I think some colleagues are working on trying to solve this sort of issue (so they have observed it too), but I don't know how much progress they have made. I'll remind them to check the forum if they find a bit of spare time...

Re: singularity Salome_Meca CFD extension install

Hello, Thanks for the feedback. Regarding coupling between code_saturne and code_aster, the old coupling based on Salome's YACS module has been broken since 2019 I believe (I last tested it with salome_meca 2017), and its architecture was a dead end (defined more for project constraints which are no...

Re: Thermal flow boundary treatment using Neumann/Dirichlet boundary conditions

Hello, I see you have used different BC types (Dirichlet or Neumann) for different velocity components, and I doubt this will work. I am not sure which BC type will be used, but the processing of the user-defined BC conditions into the coefa/coefb values described in the theoretical documentation in...

Re: creating profiles in v7.1.1

Hello, You also need to tell the probe set which field values to plot : - Either using cs_user_postprocess_values, as per the example. - Or calling cs_probe_set_auto_var(pset, true); after the probe set creation to simply output all fields output with regular probes (i.e. as set in the GUI). You can...

Re: output velocity data at each time step from the cell centers

Hello, It still seems you are opening "output.log" and looping on the global count with no filter on the MPI rank doing this operation. And the global count (parallel sum) bfore the call to cs_parall_allgather_r is commented. Unless I missed something, since you code indentation is inconsi...

Re: Epsilon output in Launder Sharma model

Hello, Not sure about this. In any case, the variable output for preprocessing should directly be the one solved (except possibly for some clipping). The Launder Sharma model is only used in a few specific cases as far as I know, so even the main turbulent experts in the code might not have very &qu...
