Any updates on the impact case?

You may find <https://doi.org/10.1016/j.coastaleng.2023.104397> a useful reference.

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...

If you could give more details, perhaps I can try to give a more detailed reply... if Re~10,000 and you want to dive 1m... does that mean the cylinder diameter is 1mm or 10m? Can the cylinder rotate or is it fixed? Is it rigid or flexible? Modeling a cylinder in CFD can be either very easy or very c...

As a part of the DIMPACT project <https://www.france-energies-marines.org/en/projects/dimpact/>, for some CFD work at Ecole des Ponts and France Energies Marines, we have done some simulations very similar to this. Some part of this has been already published : <https://hal.science/hal-03721266/docu...

Is there somewhere the full documentation of the mathematical expression library used? I tried to take a look around, but didn't find anything. In particular, I am curious if there are any demos of: * the while statement (in an attempt to create a loop) * the square_norm function (apparently defined...

To follow work presented at the user meetings between 2016 and 2019, and in the 2021 paper with Martin Ferrand, https://hal-edf.archives-ouvertes.fr/hal-03426951 , I have recently updated a repository with a few test cases. Links to source code, references, and more animations are at: https://gitlab...

Are there any connections between the EDF team and the group (Debian Science Team) that put code_saturne in their package managers ? https://packages.debian.org/search?keywords=code-saturne https://packages.ubuntu.com/search?keywords=code-saturne If so, it could be useful, especially for more casual...
