Auto-optimization?

Hey all
In some recent CFD readings, it seems some packages offer a mechanism for auto-optimization of a component. I want to do a wing study, where a few variables exist (i.e. angle of incidence/attack, various flap angles), and wonder if CFX has any ability to support this type of automated effort? Ideally, I would like to define edge conditions, and it could run through various combinations using those parameters, and a deformable mesh of some type, to either self-optimize, or to at least generate a results file for each variation. Any guidance here for a newbie is appreciated. |

matlab + matlab optimisation toolbox + proE + CFXpre + CFXsolve + CFXpost = powerfull optimisation combination

Look at this PDF file. It uses Fluent, but it could probably be done for CFX as well.

Using traditional gradient based optimisation in CFD applications is often troublesome. Non-gradient based algorithms .e.g. direct search are much more robust.
Generating geometry within optimisation loops loops is often made easier by simply manipulating a CAD package's text based journal file. |
