UDF depending on residual -- CFD Online Discussion Forums

Sasha Guest Posts: n/a	Dear, all. Is there a possibility to write a UDF that checks the residuals and gradually increases the under relaxation factors depending on them. Say, change URF for momentum from 0.2 to 0.3 if the residual of continuity hits 10^-4 for more than 10 consecutive iterations. Thank you, Sasha.
