C.C is on a distinguished road
Hi all,

I'm trying to implement by UDF a low Reynolds k-e turbulence model using an UDF. My UDF was interpreted without any error, the solution was converging when after some iterations suddenly I obtained this error:
"Error: Divergence detected in AMG solver: uds-0
Error Object: #f"
Please, in attachment you can find the residuals plot... They are converging without a oscilatory behavior. I don't know why this is happening
Anyone can help me?
Just one more thing, anyone knows if it is possible have access to information about how low Reynolds k-e turbulence models are implemented in Fluent? Thank you.
