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...

Re: output velocity data at each time step from the cell centers
Hello, You are computing g_ii before filtering the cells in the zones, so your counts can't match. Also, if you open your file on al ranks, you may have multiple issues. Do you need to do this once or twice or automate it ? You could probably do all of this easily in ParaView, selecting a zone in a ...

Re: Restart with new mesh
Hello, Regarding the EBRSM model, I'll let Jean-François provide more details or recommendations. Otherwise, regarding interpolation, the problems you will have or not have probably simply depends on the target mesh. Simply running a few iterations from start on that mesh should give you an idea of ...

Re: Restart with new mesh
Hello, The issue seems to be that the mesh quality is bad, or for example you have very thin and warped or non-orthogonal cells at the boundary. This will cause convergence issues with all variables unless you deactivate flux reconstruction. You may also try to use the mesh robustness options (check...

Re: output velocity data at each time step from the cell centers
Hello,
Are you running on a single processor ? Your code will definitely not work correcty when using MPI parallelism.
Best regards,
Yvan

Re: User meeting schedule
Hello,
The meeting is not scheduled yet, but will probably be held in late summer or fall of 2025 (after the release of 9.0).

Re: MPI Installation on Cray EX HPC
Hello, Yes, we have encountered this, and modified the src/fvm/fvm_to_ensight_case.c (now .cpp) file accordingly, to replace ":" with ".". This is due to MPICH's ROMIO MPI-IO library reserving the ":" in filename for its own purpuses (i.e. some interpretation of metadat...
