Hello friends! In the Residual Monitors of fluent ,the defalt convergence criterion is "absolute".Can I choose "none"? In some case ,it can not effect the result ,but in some others the result is not converged,that is why?

Hi Wanghuo,

I don't understand what you mean with in some cases it cannot effect the results, and in others it does not converge, can you elaborate?
I guess if you set convergence criterion to none it will not converge based on a certain value of the residuals - you disabled that - so you need to give other convergence criteria...

In the GUI, uncheck the boxes labeled under "Check"

Disabling this option disables the comparison of the residuals with the the criteria as a terminating condition and allows the simulation to keep iterating.
