One of the goals of the FreeCAD project [1] is to be a high-level interface for tools like OpenFOAM (via the CfdOF workbench [2]), and other solvers/meshers like CalculiX, Elmer, Gmsh, and Netgen.
Its modular, workbench-based, Python-around-C++ core approach provides an environment for people to make their own specialized tools, like the Arch Rebar tool [3] that was created as part of a Google Summer of Code project. [4] like airfoil design as you mentioned. There was a recent forum thread started by people interested in doing exactly that. [5]
