Relaxation - Automatic Convergence Control
 

In the relaxation setting, there is an option of Automatic Convergence Control. What does it use for?
As the default setting is "on". I would like to ask is there any case that Automatic Convergence Control should be off? Or in other words, in what situation such setting has to be considered? Thanks a lot.

you can read here http://www.cham.co.uk/phoenics/d_pol...61/chap2.htm#2 how it works. We found out that we have to turn it off when we're doing wind simulations unsing huge domains and the wind object. Perhaps there are even more cases it's usfull to turn it off.

Thanks for your reply.
