Hello everyone,
I simulated a case by CFX-solver. But the RMS value does not converge. The mesh quality is above 0.5 at ICEM. I set the timestep very small to 0.001s. (Initially it was larger, but there's still RMS fluctuation for nearly every timestep.) I copied the boundary condition setting from my classmate. It's not likely to have any problem at it. Since I'm not allowed to distribute our homework, I can only upload my CFX-solver pictures. Hope you can give me some hints about where the problem might be.
