Thanks for your advice, I've carried out following your instructions and have good results.
Now I am doing some case studies using solver MRFSimpleFoam and SRFSimpleFoam to simulation flow over rotating flat. Parameter of flat includes length= 200 mm and width=20 mm with velocity inlet 10m/s. I used Turbulence property tools on website for calculating initial boundary conditions of epsilon, k, omega...In case MRFSimpleFoam, I generated mesh model of flat which includes 3 zones fluid_inside (rotate), fluid_outside (stator), balde. However, both of the cases do not converge, bounding k and results of pressure and velocity very large. I dont know the reason why the errors appears.
I attached 2 cases (the following links) for MRFsimple and SRFSimple, could you have a look and help me identify where the problem is (due to initial boundary conditions, quality of mesh, fvchemes, fvsolution,...). I am confused but don't know where to find the answer for this problem.
Thanks for your help.
