Add Convergence Criteria

Hey, can you tell me how i can add a convergence criteria? I want the Channel395 tutorial to run until Umean <= 10^-6

Hi,

You have to post question just like in private message, the original message here is not quite clear.

Here is example case that does almost a thing you have asked for:

https://github.com/mrklein/foam-case...stop-upon-umax

It stops simulation upon Umax magnitude. To have Umean, you can either lookup mean velocity field instead of velocity in codeRead or just add averaging code to the coded function object.
