Hi everybody,

I'm new in this comunity, so hopefully you'll forgive my grammar and theoretical errors

I'm getting crazy with the solver of CFX! Sometimes apparently randomly it gives this kind of error message. And i really can't understand why.
Sometimes it works changing mesh but not always.

I'm simulating a single stage radial water pump, impeller plus volute...Steady simulation and meshes made by CFX mesher (the one in the workbench).

Any suggestions?!?!?

here the outfile:
