How do I force Fluent to keep calculation?

Dal7 · August 24, 2021, 03:30

I want a case to be calculated to 500 iterations by force.

But as you know, when the calculation done, it stops by itself (like in 100 or 221 of iterations, before 500 iterations.)

Is there any way to force Fluent calculate?

I mean if I set 500 number of iterations, Fluent calculate 500.
and if I set 1500 number of iterations, Fluent calculate 1500, whether its calculation is done or not.

English is not my mother language so, sorry for my bad English

Fluent will do however many iterations you want unless you set stopping criteria. These are usually the convergence monitors. Simply turn them off. Uncheck the boxes that say check convergence.

Ah, I think I found it at Residual Monitors > Advanced option.
Thank you so much!!
