Bill,

Commercial CFD codes are, on the whole used by engineers in commercial organisations. They are not interested in a perfect result, just one that gives them an idea "which way to jump" wrt their designs. Commercial CFD codes are all things to all men and therefore are a good compromise from the code suppliers point of view and the general users. My boss wants to get an idea of whats going to happen yesterday! He doesent want to wait ten weeks for me to write and validate a piece of custom code! The software houses continue to expand and improve their code, but it is generaly to the wants of thier users, as they're the ones who PAY for the licences! It's nice to know you can write your own code, but industry isnt interested unless its cost effective.

Hi Dan,

Just want to say that NUMECA is using AMG coupled solver from begining (1992) and that the scheme is fully second order.

The frozen rotor model in TASCflow (and the MFR explicit model in STAR) are both models for the frame of reference change across the interface. The big difference is that TASCflow implicitly couples control volume equations through the interface wheas STAR does not. This significantly improves robustness and convergence rates in TASCflow.

Dan.
