How to modify iterated time in fluent UDF

December 29, 2004, 22:49

Hi,everyone

My calculation is a coupled unsteady problem. After several periods, if the result is not meet the conditions of convergence,the calculation will be restarted from t=t0. Now , my question is ---

"How can I re-set the iterated time to the start time t0 in fluent UDF?"

Regards!

Hi! you have to type in the TUI: (rpsetvar 'flow-time 0)

(NOTE: you have to type the parentheses too!) Now I try to do that using a UDF and let you know. Luca

Thank you Luca.

Is your method unique? Really, no other methods?

MMH.. I should think it over. Maybe we can find a method to use a UDF...we should look at the headers file and find something to initialize the flow-time. Luca
