TypeR is on a distinguished road
Hi, I tried to conduct a near wall mesh refinement study on a 2D NACA airfoil with 6 levels of refined mesh spacing near airfoil (from yplus=0.2 to 10). Only the coarsest mesh gives the stable result(pimpleFoam). Other simulations generate oscillatory results, and a typical pressure field is attached.

I used linearupwind as div schemes, even switched to upwind the problem persists. Please help, thanks!
