monitoring steady state in openfoam
 
Dear Foamers,

how could i know that my SIMPLE solver (steady state solvers) reaches the steady state? by monitor change in values only or, there is some commands or some thing else i can use.

thanks in advance :)

Hi,

I think we have to judge the convergence in a comprehensive manner
based on the followings:

1. Residuals history
2. History of physical quantity at monitor points
3. History of values such as pressure drop, drag etc.

Hope that helps,
Fumiya
