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 ...

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 ...

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 ...

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 ...

Water waves

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:

Re: Problem with libple.so.2

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 ...

Re: Problem with libple.so.2

As a "I have the same" comment, on Ubuntu I see the same problem. While not that big of a deal, if there was a general solution that fit into the install stage, it would be preferred; for now I just run "export LD_LIBRARY_PATH..." each time in a new shell, as I keep multiple versions on my machine ...

Re: CoolProp materials

I attach a simple xml but I can provide a more detailed case that corresponds to a more realistic benchmark if needed.

In this case, if I just run "~/CS-7.2.0/bin/code_saturne create -s TMP", then go to Mesh, set "Generate cartesian mesh" (generating a single-cell mesh, though Cartesian is normally ...
