Convergence issue due to high rotational speed -- CFD Online Discussion Forums

Shuttle New Member Shuttle Join Date: Jul 2022 Posts: 5 Rep Power: 3	Hello, I am currently simulating a gap between the rotor (rotating at 12000 RPM) and stator with eccentricity in Fluent, however, I am getting a reverse flow both at the inlet and outlet, at inlet some reverse flow is expected, but at the outlet not. I am trying to verify my model based on a research paper. Because of that, I am also having convergence issues with continuity. I found some solutions on the internet but they are somehow not working. I didn't try to extend my domain because of the dimensions given in the paper. Any suggestion would be nice, as I am stuck due to that in my work. MicrosoftTeams-image.png MicrosoftTeams-image (1).jpg
