Re: How to check face joinings

Hello, Yes, thé theory guide provides more details but face joining will split faces if necessary, subdividing "classical" cells into general polyhedra. This can slightly degrade mesh quality at a local level, but measuring the impact is difficult/requires extensive comparisons, and can have more im...

Re: Convergence criteria based on residuals in code_saturne?

Hello, There is no automatic stapping criteria in code_saturne, as tuning such a criteria is quite tricky and possibly and model + options+mesh dependent, but you could use the values output automatically in residuals.csv to define such a criteria (coding it in cs_user_extra_operations.c for example...

Re: How to check face joinings

Hello,

With a visualization level of at least 1 in cs_join_add, a postprocessing output dedicated to that will be output, so you can check joinings. You can also check what is still in the boundary visualization output, as joiined faces become interior (not boundary) faces.

Regards,

Yvan

Re: Issue, and questions, regarding CoolProp fluid library

Hello, I'll look at your case within a few days. Regarding tables, CoolProp already contains an option for tabulating data, but I am not sure how efficient it is. If is is fast enough, the simplest option would be to use that, otherwise, simply build external tables, either simpler coarser, or with ...

Re: Installation on cluster

Hello, Thanks for the feedback. This was fixed November 2018 for the v6.0 and master branches, but was not backported to v5.0. I'll fix it in the next v5.0 release (but there might be other Python 3 bugs in the GUI), which will be maintained until spring of 2021 (until v7.0 is released). Best regard...

Re: Issue, and questions, regarding CoolProp fluid library

Hello, I do not know why you have this error. Could you provide an (ideally very small) test case ? For your other questions: - The CP backend can be used both from the GUI and user (C) functions in theory, with some settings that are still hard-coded (such as using tables or not) - I do not know wh...

Re: Installation on cluster

Hello, Environment modules were detected (and probably loaded) when running the "configure' step. It is possible that those modules are not loaded correctly when running (depending on the module system variant), as they are loaded by a Python script. Starting with code_saturne 5.0.10 (the latest 5.0...

Re: Installation on cluster

Hello,

Can you post the config.log ?

Re: Installation on cluster

Hello,

Yes, this could explain the issue. Do you have environment modules loaded at install time ?

Re: Installation on cluster

Hello, Thé compile log indicates the link with libxml2 fails. It is possibly due to not having the libxml2 dev package on the computer nodes (i.e. libxml2.so.x present but not the libxml2.so link). Do you use "code_saturne submit" or the GUi, or submit a runcase directly (not recommend ed for the ab...
