Several years ago the DoD’s HPCMP started a large (at the time it was slated to be over a hundred million dollars over ten year) software effort to develop HPC applications that non-specialists in the acquisition community within DoD could use to guide their projects. The effort is called CREATE, and is headed up by Douglass Post at the HPCMP (he’s originally from DOE, and is a swell guy). CREATE is divided into three efforts aimed at specific communities — full airframe simulation, ship simulation, antenna design — and a cross-cutting fourth effort that builds common software tools.
NCSA’s hosted Bob Meakin last year, and I just found the video of his talk about the air vehicle portion of CREATE. You may find it interesting (it runs about 47 minutes).
