I've set up an optimization case for discretizer+openfoam: http://www.discretizer.org/files/opt...utorial.tar.gz Björn

Maybe you can use your imagination? Probably all airfoils are optimized?
Most important is to be able to set up a HUGE function. INPUT => HUGE FUNCTION(CFD-analysis) => RESULT So basically, create a script with a couple of input arguments. Suppress all stdout messages except the result at the end :-) Possible way of solving it(free software path): 1. use gmsh for geometry creation, create a surface mesh 2. use snappyHexMesh for volume mesh creation 3. use OpenFOAM for CFD-calculation 4. get the output from force monitoring via scripts Use opt4j or Dakota as optimizer. The commercial path: 1. Ansa for geometry and surface mesh creation (via morphing) 2. Star-CCM+ for volume mesh and postprocessing (via java scripts) Use ModeFRONTIER as optimizer. Björn
