Hello FOAMers,

I asked the same question in Running and Solving forum but I'm not sure if it was the right forum for my thread. I'm new in OpenFoam 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.

How can I ensure that OpenFoam reads the fvSolution every timestep? Please can anybody help me with my problem?

thanks and best regards, Mike
