Pierre1 is on a distinguished road
Typically there are two convergence criteria

1. Residuals drop to enough low value
2. Output parameters (the parameters we care about in the simulations results) don’t change anymore with more simulation iterations

It seems that we can only set up the 1st criteria in Fluent and CFX. Regarding the second one, we need to either monitor by eyes or setup to run absolutely enough iterations number to make sure the simulations satisfy it. Both of these two ways are costly.

Anyone has a better way to set up the second criteria?
