The case is here. https://db.tt/EOi1wRN3 It is a 2D VAWT. The simulation runs fine and gives appropriate results compared with experimental data. However, whenever I stop and restart this case, I get weird velocity oscillations in the rotating domain and at the AMI, and a big pressure rise just at the restart. Then everything is smoothed out thanks to diffusion... Any help would be greatly appreciated. Last edited by bennn; November 29, 2013 at 09:27.
