code_saturne User's Forum

Hello Daniele, When code_saturne does not find a partition input file matching a given number of MPI ranks, it simply recoputes the partition (so saving a partitioning is useful mostly for debugging, when we want to ensure we are in the same conditions as a failed computation). So I would guess the ...

Hello, The cs_user_source_terms can handle both source and sink terms, so you can use it for this. The most difficult part here is probably computing/measuring how much heat is accumulating, so as to know how which value to assign to the source term. A relatively simple solution might be to compute ...

Hello, This issue was analyzed on a separate support channel. For other people reading this post, the issue seems to be due to the build process used by the IT support team installing the compilers locally as prerequisites, but not providing them in the final install. We had a similar issue about 2 ...

Hello, Yes, creating another post in the "code_saturne usage" section will be better. I will probably also move this thread from discussion to "installation", as it started as a general discussion subject but evolved into an install issue. If the computation is stuck, I recommene...

Hello, We may be missing a way to tell the GUI that a Cartesion mesh is defined by user-defined functions and not the GUI (previously, the SRC would overwrite the GUI, but now they can be added). I think you can work around this by defining an "empty" Cartesion mesh in the GUI, defining 0 ...

Hello, Yes, you can set part of this behavior in the GUI ("one probe per cell"), and can have finer grained controls in user-defined functions. Check the Doxygen (html) documentation for cs_probe_set_t. The default behavior will also depend on whether the mesh is fixed (where we snap coord...

Hello, To run in a manner similar to non-containerized installs, you would need to call either "code_saturne run' or "code_saturne submit" from within the container. "code_saturne submit" will first prepare the execution directory "immediately" (i.e. run "code...

Hello, To understand how code_saturne runs using SLURM, there are 2 important points in the documentation : - Configuring SLURM in the post-install step : https://github.com/code-saturne/code_saturne/blob/master/INSTALL.md#recommended-post-install-steps. (if you do no do this, you will need to work ...

Hello, Here is another, more complex example, with a target velocity. In this case, we measure the flow rate so as to compare it to the target, and adjust the source term accordingy. This example also handles restarts using this, and used various notebook variables for parametric data. I'll let you ...

Hello, I think the velocity should converge to that balancing the source term and the friction after a number of iterations. To choose the target velocity, I'll try to find another example. I think we had one at some time, but am not sure whether I am looking at the wrong example or if the setup was...
