Hello, I recommend installing version 4.0. Versions 3.3 and 3.2 are "short cycle" development releases, and are not maintained anymore. When the code says it can't read MED files, it means it was installed without MED file support. A solution would be to reinstall it. You can download the ...

Hello, The "isca" numbering is a specific indirection, which is only used for scalars, and ivarfl to map resolved variable to field ids. The "low-level" field functions use a "flat" numbering, so you should not use: call field_get_id_try('var1',id_name) call field_get_v...

Hello, In version 4.0, you can also use a higher level function to tell the code you are creating a property field (which manages a few additional setting). Check cs_user_parameters.c examples. The approach should work so far as I can think of. But in cs_user_extra_operations.f90, are you using : fi...

Hello, There are 2 possible issues in your case: - you have a very refined mesh near the wall. This is good for low-Reynolds models (the y+ near the wall is near 0.6), but maybe to refined for high-Reynolds turbulent models. - you have very high CFL numbers. You could reduce the time step, or use a ...

Hello, You don't need Qt for the OSMesa build of ParaView, so you should be OK (as long as you use a separate, "standard" build on a workstation with the co-processing script generator plugin). In the section relative to ParaView in the Code_Saturne install doc, the option used to disable ...

Hello, If you have any luck, OSMesa should be available as a package under CentOS (it is at least for Debian, Ubuntu, and Arch Linux). If you do not have administrator privileges, of course, you need to install it in a user account. This is a a pain, as you've probably already guessed. For my builds...

Hello, I don't think using VNC will be a viable option, except for testing on a single node, because if the code is run in batch mode, the execution environment will probably not have an X11 "display". Add to that the the graphic cards are probably different on the front-end node and compu...

Hello,

How would you write the expression you need in the C language, assuming t is the time and q_v the volumic flow rate ?

Hello, I'll check with colleagues tomorrow to see if there were changes (fixes) in the Spallart-Allmaras model between 3.0 and 4.0. I'll keep you informed. In any case, for new computations, I would recommend upgrading to version 4.0. Also, regarding one of your previous mails, for your LBM model, i...

Hello, 2 lines just after one one you cite (in 4.3.6), you have an important addition, explaining that you need a second paraview build, for postprocessing. You can also use a single build, but in this case, you will have graphical windows open during computation, and the code will only run using Ca...
