Flow Courant Number in Solution Controls
What does changing of the setting "Flow Courant Number" inside Solution Controls do? Or, is there a link to the theory behind this setting?
Flow Courant Number has an effect on convergence of my model (which is micron scale, FSI, and creeping flow) but I have trouble finding a good setting, and convergence is precarious. |
I can't find it in the Fluent help either. Can Anyone tell me where to find what "Flow Courant Number" numerically means for steady state calculations?

I have posted a detailed explanation here:

URF or Flow Courant Number
Thanks O.J.,
I'm wondering, if you set the underrelaxation to one value and the flow courant number to another, which one will Fluent use? |
I have answered this question as well:

Sorry to bring up tis old thread, but I think it's still relevant.
Just to make sure I get this right: Flow Courant Number and CFL is the same, right? |
