I write an udf to modify the source terms and the diffusibility term, and i and e are solved as scalar quantities. I obtained the following error: Error: Divergence detected in AMG solver: uds-0 Error Object: #f I have no idea why obtain it... Please, anyone have an idea why it happens? Also, in the udf i don't have a part for the initialization of the variables field. I think that is not necessary in the udf, is this true?
