Hello, What do you mean by "calculation gets corrupted" ? - Does the code crash on an invalid memory access error ? - Or are the results bad/unexpected ? If the code runs but provides incorrect results, you may have a mesh quality issue. Notably, if cells inserted in the viscous layer have...

Hello, I know the handling of "per variable" time scheme is a complicated mess, with some options that have been available for years but never really tested, and others which may be missing but would make sense. I am not too well versed in this part of the code, but will ask some colleague...

Hello, I'm not sure what would be best here. I'm not fond of working on a component by component basis for vectors, which should be invariant wrt the frame of reference. I'll need to discuss this with colleagues who participated in the implementation of the scalar schemes. Obviously, since the code ...

Hello,

The error is line 1957:

configure error: cannot find PyQt5 support (>= 5.0) or PyQt4 support (>= 4.5), Graphical User Interface cannot be installed.

You need to install the prerequisites or disable the GUI.

Hello, I would guess you do not have MPI on.your machine. It is strongly recommended to install it with code_saturne. Scotch is optional, and useful only if you have MPI. Also check these recommendations : https://github.com/code-saturne/code_saturne/wiki/Pre-installation:-Linux-distribution-package...

Hello, I am not sure about this. I checked the code today, and I seeat least some schemes require defining a min/max value which is easy to define for scalarsbet less so for vectors (I.e. do we limit the norm or the components, or a combination thereof ?). And as far as I know, the other options all...

Hello, The issue is probably that not all schemes implemented on scalars were implemented for velocity. The implementation goes back to a few years, but was not really used since it was not available in the GUI and poorly documented. Since these schemes were only strongly tested on a 1D verification...

Hello, The residuals definition might vary from code to code, so its interpretation also. The definition used is in https://www.code-saturne.org/documentation/8.1/doxygen/src/cs_ug_output.html, at "Analyzing the output/Checking the convergence". Even on a "converged" computation,...

Hello, Yes, Getting the right combination is a bit tricky, and compatibilty tests are done too late (it would be much simpler if the combination was tested after the setup stage, and options such as slope test possibly adjuster automatically). In v8.1, I added the possibility of choosing NVD schemes...

Hello,

I'll need to check with atmospheric model specialists, but i would assume you can simply change the viscosity in the GUI.

Best regards,
