Re: Use of Azure Batch or Google Cloud HPC to run simulation on cloud cluster
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...

Re: cs_mesh_cartesian_define_from_csv
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 ...

Re: Automatic change in monitoring point
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...

Re: Use of Azure Batch or Google Cloud HPC to run simulation on cloud cluster
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...

Re: Use of Azure Batch or Google Cloud HPC to run simulation on cloud cluster
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 ...

Re: streamwise periodicity
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 ...

Re: streamwise periodicity
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...

Re: use a deformed mesh (med file)to restart code saturne calculation
Hello, Graph2 seems better adapted to an iterative solution, assuming the flow has a significant influence on the water tank. What i not clear to me is the type of flow you are trying to compute. Most FSI studies done with code_saturne involve interaction with a complex flow, such as flow induced vi...

Re: use a deformed mesh (med file)to restart code saturne calculation
Hello, Regarding your first question, does the deformed mesh have the same topology (number and connectivity of elements) as the original one ? If that is the case, you can simply: - Create an empty "checkpoint" directory. - Copy the .csm file for the new calculation into it. - Copy the ch...

Re: Why is CS Open Source?
Hello, Only a small portion of the code_saturne code has been publicly funded, so the argument is not a moral one. In practice, codes would not have been open-sourced if at least part of the teams had not been interested in open source, but the moral argument is not one which would hold much weight ...
