Pressure Far Field Boundary for low Mach Numbers

Hi there,
ist there a minimum for the Mach number in pressure far field boundary condition? Because for Pressure 90000 and Mach 0.1 there is no chance for convergence. Increased quality and simplified the mesh but residuals won't decrese. By looking for residuals contours of velocity and turbulance modell, they are very high in the complete mesh, what I find doesn't make so much sense. With a badder mesh and Mach over 0.3 it's super easy converging. So is it possible that's I have to refine it so much to get the little compressible effects or is it just not possible with this boundary condition. Thx in advance! |
