Hi all,

How can we access to the under-relaxation factors, mainly for temperature ans species? I need to control them automatically during the simulation. Is there any macro or something else?

Any help will be appreciated.

Godd afternoon MASOUD,

Iīm working in a laminar diffusive flame in fluent, and I was thinking on use some kind of automatic under-relaxation factors (in Fluentīs option or with an UDF).

Please, did you discover how set up fluent to automatically change the under-relaxiation factors? Or itīs not posible to do that?
