K-omega documentation and initialization

While checking drag coefficients on a plate under steady conditions, came across an interesting question - is there a citation for where the k-omega initialization comes from? For sure it is problem specific and there are different choices one can make, but comparing with default choices in other mo...

Re: Measuring forces

I confirm that if this is not checked in the GUI (which the hover text makes reference to ipstdv which hasn't existed since v7, it seems), then this hides the boundary stress not just from the output files, but also cs_user_extra_operations (unclear if that is desired behavior or not). By chance, ar...

Gradient reconstruction

In the current GUI, there is a parameter for "Gradient reconstruction type" in the Numerical parameters panel, but there is also a sub-panel "Gradient" with very similar information under Equation parameters. Is there some documentation about the difference between the two, or do...

GUI issue : local mesh directory

For info, it appears (at least in an old 8.1-alpha) that if a setup.xml file specifies a local mesh directory, it is not displayed in the GUI, resulting in a situation where a setup may not work, and without any way to fix it from the information proposed by the GUI.

Ah, great, thanks. Any chance there is an example with the GUI? Or is this not operational yet?

Time tables

Are there any available (simple, if possible) examples showing how to use time tables (e.g., to define a boundary condition)? I have not yet found it in the documentation.

Re: Documentation, "4.5 Advanced topic"

FYI, this is now apparently 4.6.2 of https://www.code-saturne.org/documentation/8.0/theory.pdf . That said, the link to the programmers reference to iphydr at the end of the section, https://www.code-saturne.org/documentation/8.0/doxygen/src/structcs__stokes__model__t.html#iphydr , is apparently bro...

Re: Best way to export force coefficient data to files

For saving to text files, there are a few examples in src/user_examples that do exactly this, such as https://github.com/code-saturne/code_sa ... culation.c
