Hi, Can you try the develop branch or SA instead of SA_NEG. We fixed an issue in SA_NEG that could cause this type of oscillation. However, I suspect it is...

Hi Jean, Sorry for the delay. The hypothesis I have for the less robust behavior of periodic BC's is that the linear solver is not completely aware of the periodicity....

Hi @jf-thomas, hopefully this is still of interest to you, please have a look at the branch from #1585 it seems to fix the issues of your example problem. Note...

Hi @jf-thomas, was there a benefit in the end? Were you able to get better convergence in the cases you were working on?

Hi @jf-thomas no worries, thank you for the update. Just to clarify, are you referring just to the small example problem? Or also to the 2.5D wing section?

Brilliant, thanks. I'll put some time into finishing that pull request.

My guess is that the direction of the unit normal and unit tangent are not relevant, because we always use them for things like `(v.n)n` and so the sign cancels....

Disclaimer: I'm not a turbulence specialist. With that said, that definition of delta looks dodgy, what is the physical meaning of "rectifying" a distance vector to have all components positive?...

WIP #1622

@GomerOfDoom is this something you can look into? Maybe there is an easy fix to make this consistent with literature.
