Attached video shows first evolution of flow for the case. The xml file I used is attached. I tried to operate later versions with this using the "code_saturne run -p setup.xml" with no real success. I would expect of this xml file to be the messenger between the gui and the code, leading ...

I have learned to live with these buttons turning red each time the Initialization tab is left and then returned to. Your case is running on Code Saturne v5.0.4. I just downloaded and build the present v5 (v5.0.13) and with that your case does not run. I then recompiled a v5.0.4 to see if my build e...

In my experience ... If you already have a working Salome environment for geometry meshing and maybe postprocessing there is very little, if any, benefit from the integration of Code Saturne with Salome compared to the integrated gui. I actually also prepare a separate installation of Paraview above...

Hi Yvan.

Thank you very much. This is highly appreciated. I have recently had my computer occupied by parametric investigations on air-air ejectors so I have had good use of the compressible module.

Best regards and thank you to all the good people and EDF who made this possible.

Hi Christopher. See attached simulaton of your case, generated with v5.0.4. I get the same boundary condition error with boundary flow on mass basis. So using the area of the boundary surface in the mesh and my best guess om a boundary density I entered the boundary flow on a velocity basis instead....

Hi again. This behaviour seems to persist on all versions I have tested after v5.0.4. In an effort to locate the cause and rule out the possibilities of a defect build environment, I most recently made the following: I made a fresh install of Debian 10 (Debian seems to be the mother of several mains...

Just for fun and for visualising physics (self education) - Model a de Laval nozzle at 1 atm and at 0.1 atm for comparison. Animation dumps: 1.0_bar.gz 0.1_bar.gz If you look, observe that time is not linear - postprocessing writes are per n'th step not per units of time. vlcsnap-2021-03-14-21h18m37...

Might be caused by compilation environment issues. I close the topic for now.

Hi Yvan, and thank you. I just checked the installation log from the compilation of v5.0.4 back in 2019, and it was built on Python 2.7/PyQT4 whereas the more recent builds were on Python3/PyQT5 (both are available). I link up against hdf5/cgns/med/scotch libraries of Salome-MECA 2018 which are Pyth...
