Hello. Thanks for your info. Built-in inflation is cool! AFAIK, it's unique to Saturne. Will wait until it appears in GUI for more convenient use.
Generally speaking, built-in mesher is another complex task. Here we come to a complete set of geometry import, meshing, preprocessor and solver, as for ...

Hello, thanks for your info. Hope there will be more settings in your new XML and solver control approach. It's fine that Saturne keeps developing unlike almost all other software (I mean real development, not version number change or killing interface with black and white "flatness").
Maybe some ...

It just means that confugure cannot find PyQt of required versions. Check what versions you have, then search Internet for method installing on your distro. There may be a repository package or you need pip3 .
Also, newer Saturne needs C11 C++ or you will catch strange compile errors. So use up-to ...

Thanks for your answer.

I use Saturne 8.0.4 now.

I have never made any CFD code so I don't know details. My idea was to take a user example and modify the number of iterations. The code is as follows:

cs_multigrid_t *mg;
mg=cs_multigrid_define(-1,"TempC",CS_MULTIGRID_V_CYCLE);
cs_multigrid_set ...

On a workstation, you need to take into account a memory bottleneck. With DDR3 you cannot use more than [2xMemoryChannels] cores, with DDR5 the limit is not as strict and at ~[3.5xMemoryChannels]. For example, if you have DDR3 Xeon with 4 memory controller channels all with DIMMs connected , you can ...

Yes, its'strange specific Saturne problem with Outlet BC. To solve this, you need:
1. Outlet extrusion with cell size comparable with main mesh.
2. Straight flow at outlet with no recirculation zones! Add more extrusion or even small local resistance if needed.
In some cases it doesn't work because ...

Hello. It's an old question, but it's arised again so I needed to cope with it somehow...
In some situations, like start of calculation or convergence problems, Saturne make lots of linear solver iterations (10000+). It's not compatible with practice when we need just to pass through this period ...

Hello. I'd try to compile with OpenMPI 1.8.4 because I found newer versions of OpenMPI cause unpredictable hangs of calculation on my system (local CentOS-7.5 machine). Newer does not mean better not only with music, in many cases with software also. For example, old versions of Torque and Ganglia ...

Hello. Sorry, was busy with our cluster maintenance. Thanks for advice.
Here is what I discovered.
1. Temperature definition and CS_F_(h) coredump. These errors was fixed with current " 9.0-alpha " development version from GitGub. So, generally, initial questions I posted are solved with current ...

Hello, thanks for your answer.
Actually, I don't need specific operations with turbulence field. I just need to add relaxation because it stabilizes the solution. Is it enough to set Rij relaxation factor and flux reconstruction flag not touching tensor components? I mean:

field=CS_F_(rij ...
