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...

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...

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.

Any news for possible 2024 (or 2025) meetings? https://www.code-saturne.org/cms/web/community/meetings

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

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.

Any updates on the impact case?

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...

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

Ah, so then this is motion in 2D, but a 3D flow (so not really a 2D problem)? If you would accept a fixed velocity of motion, to get the force / impulse, I have some experience with this from the VOF side, and from what you are saying may be enough for this initial phase of impact. Overall, it may b...
