Default Convergence Criteria - airfoil sim.

What it's the recommended criteria for an airfoil simulation?

It's good enough an RMS < 1e-4 or it's better a MAX < 5e-4?

Reynolds max. 600e3 - AoA between -2 to 12.

Thanks in advance,

Monitor your forces and see if they are still changing to help you decide...

You should also monitor mass and momentum imbalances to make sure these are small (> 0.001 or smaller depending on how accurate you need to be).
