pseudo-transient
 

HI,

I've had some problems with the convergence of the buoyand flow, and started playing with the analysis settings. and I have a question: what is the pseudotransient mode??? it seems to be coping with my problem very well, but I do not understand: it is the same (or not) SIMPISO, with the same relaxation factors, but it works much better than normal steady solution...

COuld you perhaps advise me some good book about it? Because the Star Methodology is totally not understandable for me.

Thank you
