Re: Time tables

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: OBJECT IMPACT ON WATER

Any updates on the impact case?

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

Re: OBJECT IMPACT ON WATER

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...

Re: OBJECT IMPACT ON WATER

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...

Re: OBJECT IMPACT ON WATER

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...

GUI math expression documentation

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...
