Fatal overflow in linear solver

Hi Glenn,

I used cylindrical coordinates just to define the flow direction. And I experienced that CFX does the transformation itself. Also, I tried cartesian coordinates and it did not coverge.

Thanks for your consideration

Run the simulation again, but this time include the equation residuals and produce an output file just before it crashes. Then have a look in the post processor for where the region of high residuals are - this might give you a clue for the next step.
