MRFSimpleFoam convergence problems
 
Hi all,

I'm doing a complicated low-fan simulation in OF 2.1. with MRFSimpleFoam. 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
