Re: model validation
Hello, If you get different results each time, there may be some memory corruption, which indicates a bug... How large is your test case ? If it is not too big, I would be interested in running it under a tool such as Valgrind or a build using AdressSanitizer to check for a bug in code_saturne... If...

Re: Cannot use TVD schemes
Hello, Yes, I would have been interested in testing this for some cases to improve robustness, but was stuck at this point, and am already too busy with other parts of the code to realistically expect to work on this in the near future. But helping others do it might add a bit of leverage. Best rega...

Re: model validation
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...

Re: Second-Order Temporal Discretization Except for Turbulence Model Equations
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...

Re: Cannot use TVD schemes
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 ...

Re: Problem installing Scotch - automatic installation
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.
Regards,
Yvan

Re: Problem installing Scotch - automatic installation
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...

Re: Cannot use TVD schemes
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...

Re: Cannot use TVD schemes
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...
