I've always used RSM for cyclones, but happy to see SSTCC can give a good result. 

Mesh dependence looking purely at cell count may miss the effect of clustering cells in certain regions. I'd also check the experimental data: I'm always wary of trusting either experimental or CFD results over the other when there's not complete agreement. 

Pseudo transient may miss the core precession, so you may need transient. However, have you read any of Nick Syred's papers? They're fairly old but will be worth digging out.Â
