thanks for your reply,Bob. all the residual were below 10e-3, steady simulation was used about 100000 iterations, the air was defined as a velocity inlet, at this condition, the air velocity was 22 m/s, the stirred top was degassing condition. I have checked the mesh, the rotate region and station region have been shared topology in SCDM, the mesh were commom nodes.
