Hello FOAMers,

I'm new here and i have a big problem.
I'm writing my bachelor thesis in a company which want to use OpenFOAM instead of Fluent in future. It works fine, but OpenFoam is much slower than Fluent to find the solution. The calculation is running on a 64 core cluster and I'm using chtMultiRegionSimpleFoam.

So i decided to implement a fuzzy algorithm control for the relaxation factors to get faster convergence and more stability. For the fuzzy algorithm it is necessary to write every timestep new relaxationfactors. But now I've a problems. The problem is that OpenFoam don't read the fvSolution every timestep which is necessary for my relax control algorithm. In the global controlDict i use timeStepMaster for fileModificationChecking.

Please can anybody help me with my problem?

thanks and best regards, Mike
