As I'm getting convergence problems, I'm thinking about two things to avoid it: 1. bad initial results - how can set the rotating field for U in the rotor zone? 2. starting at a much lower rotational velocity and ramp it up by hand. i'm thinking about to use the changeDictionary tool Best, Attila __________________ I am doing CFD Consulting Services.
