I continue to get run failures even though the mesh looks good and the simulation starts okay. I tried changing mesh and added regional meshing with no luck . Please help, thanks.
Here are the latest notes from Run 4 at 200 rad/sec (about 90 met/sec tip speed).
Job was prepared successfully.
Run pre-processing finished.
Detected divergence of the linear system solver. Consider lowering the relaxation factor for fields: Ux, Uy, Uz.
The solution diverged, please check your simulation setup. Divergence can also be caused by bad elements in the mesh. Such elements tend to exist near walls and sharp corners. Visually inspect your mesh to locate them and re-mesh with additional refinements in their vicinity. If you are confident about the mesh-quality, please reduce relaxation factors and use more conservative numerical schemes.
