I am performing an analysis on a NACA 2412 hydrofoil that is positioned at a 4 degree angle of attack. I want to test for cavitation formation. However, I am first doing it for velocity and pressure magnitudes. The test will run at a speed of 15 m/s. I had an issue when first trying this where there was a pressure problem near the trailing edge for being really sharp. I have made a fillet on the trailing edge to elimnate that sharp edge that caused the problem. I am wondering if the mesh I created for the new modified hydrofoil will work.
Hi @VorCavPro, thanks for posting on the forum and welcome to the SimScale Community
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
