hello everyone,iam trying to simulate flow on a horizontal axis wind turbine using using SRFSimpleFoam mixer tutorial

i made the geometry and the mesh of 1 blade using ansys and i made the meshing on 1 blade with periodic boundary condition and after that i exported the mesh and the openfoam read the mesh file using (FluentMeshToFoam command)

actually iam trying to modify the tutorial of mixer to be my case ,to be honest i faced some problems such that

1- when converting the mesh from ansys to openfoam it converted correctly but the periodic faces haven't been recognized it was patch type in the boundary file so i used createPatchDict to transform to cyclic and it has been transformed then i run check mesh ,but there was 1 check mesh failed (due to skew faces) i don't know is it ok here to run or not ?
2- but when i run the simulation but it crashed because of the residual of time step error increases (divergence problem)

i tried to modify the solver and non orthogonal correctors but same error appeared

so is the problem that making the mesh (having a periodic boundries) with external mesher then converting it to foam is it ok or i should use blockmesh and snappyhexmesh so openfoam can understand better?
