Design environments incorporating knowledge based engineering are increasingly being developed. Examples include the AVEC environment developed by the Air Force based on the commercially available Adaptive Modeling Language (AML) product as well as the commercial design frameworks of ModelCenter (Phoenix Integration) and MDICE (CFDRC). Our proposed componentized geometry toolkit will readily integrate within such environments, giving immediate relief to the needs that have crippled progress in design optimization for the past two decades. The potential markets for our software are very broad. Our software can be used for fluid dynamic applications in the aerodynamic, automotive, biomedical, turbomachinery, and hydroelectric fields as well as for structural and electromagnetic applications. Each of these markets can immensely benefit from automated design optimization, provided that flexible geometry manipulation is no longer an impediment. Several design-oriented projects and design environments are being developed at the various NASA Research Centers, including the NPSS, CoHAVE, ADVISE, FUN3D, TetrUSS, and CART3D design environments. A common requirement of each of these design environments is the need for shape parameterization and modification. Our proposed geometry toolkit approach enables a very flexible and elegant means to construct, refine, and explore combinations of techniques that produce different final geometry shapes. Our project will make available componentized geometry-related technologies that address critical areas needs to enable next-generation design optimization. NASA can immediately benefit from our design-oriented components in its design efforts as well as in analysis-only environments in which rapid shape modifications are desired.
