Have you checked your mesh?
I had a similar error. Turns out after performing some transformation the mesh failed 4 check test! |

1. May be you should try more nCorrectors and lesses nOuterCorrectors
Code:
PIMPLE { correctPhi yes; nOuterCorrectors 1; nCorrectors 10; // or 20 or 50 nNonOrthogonalCorrectors 1;} |
