About convergence criterion
 

Fluent offers as stop criteria: when certain residual has reached a value, (which we may choose to be absolute or relative to the value in the 1st iteration), stop iterating.

I was wondering if it is possible to fix the criteria to be "stop when the residuals are not changing anymore". I don't find such an option. I don't find either how to manage that by means of UDF/scheme, since I don't know how to retrieve the residuals value... can anyone help here?
