I'm trying to use sliding mesh method (but I don't know if MRF could work better) due to I want to simulate velocity distribution in order to change impeller geometry and determinate its possition inside the tank. I am also interested in moments in order to know power. I don't know if I have enough mesh quality since I am using ANSYS academics and it is a huge tank (3x2 meters).. My residuals are a bit higher than 1e-03. How much time should i expect convergence? And how many cells would provide a reasonable solution? Thanks!
