Relaxation factors/quick question

atareen64 · February 18, 2011, 14:57

Hi All,

I have a simple question: how do I decrease/increase relaxation factors in openfoam? I am passing fluid through a tube at transonic velocity and I get the maximum iterations exceeded error. I have a hunch that If it might have to do with my relaxation factors?

Can somebody please tell how to change relaxation factors or what the are?

Thanks millions!

Ammar.
