FSI + kOmegaSST turbulence model

[vidulejs]

As we agreed, this is the pull request where we can discuss the issue with the Poisson wall distance calculation and eventually create a new turbulent FSI tutorial. This case would have to be modified to have a higher Re number.

Thanks for pushing this! @KariimAhmed could you please try to adjust this case to reproduce your issue? It would then be much easier for us to fix.

After we have a fix, we should indeed convert this to a new perpendicular-flap-turbulent tutorial.

@vidulejs I know this was meant to be a complete draft. I just went ahead changed some formatting things to make this already easier to review and transform into a tutorial, so that you can focus on the actual issue. Please pull from your branch.

Thanks for fixing the formatting @MakisH!

Just to re-iterate from our conversation, we want to create a fully turbulent FSI test case to see if an adapter-related issue appears. We should start with increasing the velocity, to achieve a higher Reynolds number. The numerical schemes will probably need updating, because the turbulent energy dissipation rate omega was exploding.

I noticed I accidentally pushed the wrong wallDist method, but during our meeting I had the Poisson method and the case was running succesfully.
