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...

Re: BC with convection + radiation to the ambient
Hello, I do not think you can access this value from the GUI, so you need to handle this with a user-defined function. It would indeed be an interesting addition. Actually, since the GUI-defined user expressions are used by the code to generate and compile code similar to that of user-defined functi...

Re: Automatic change in monitoring point
Hello, Yes, the interpolation is based on a 1s-order Taylor expansion. There is currently no better option. The interpolation is actually designed so that a user could pass their own interpolation function, but no such function is available. One solution would be to use cell to vertex interpolation ...
