2nd order equations not solving well
Does anybody have any tips for getting 2nd order equations to converge? I'm modeling cyclones and from what I see the data appears to be better than the first order, but it won't actually converge.
I've been running on both RSM and KE steady state models. I started iterating after the first order equations converged. Any tips?

run rsm and presto or bfw for pressure and also try double precision solver. also ramp up flow rate gradually.
