Performing a simulation on a NACA 2412 Hydrofoil at a 4 aoa

Hi @VorCavPro, thanks for posting on the forum and welcome to the SimScale Community :handshake:

Looking at your mesh near the trailing edge, now it’s visible that the boundary layers don’t seem to be breaking:

Which should suffice for the convergence of the simulation. Looking at the meshing log, your Non-orthogonality still seems a bit high:

Taking a look at this article might be helpful in solving meshing issues:

A final piece of advice is to define area averages to the inlet/outlet so that you can manually observe the convergence of the run there.

Is that helpful?

Cheers
Igor
