Hello,
I have some concerns regarding the procedure when ramping up my values (initial flow velocity, omega for rotating geometry, ...) when having convergence troubles. I want to follow the advice and start with low values and use the converged solution as my initial values for the next simulation. I am using MRFSimpleFoam with RNGkEpsilon. The values for k and epsilon depend on my Reynoldsnumber. (for Re = 180000 I get k = 0,164 and epsilon = 1,778). Will I have to adjust them for every simulation when I start with lower omega values for the rotation (resulting in lower flow speeds and lower Re)? Greetings, Amelie |
