Anyone used NASA software to design compressors...?

Hi there! I'm working on a "simple" hobby project that needs a small custom centrifugal compressor, and was evaluating using the freely available (at least to US Citizens) NASA software:

- CCD/QUIK (design using performance/sizing requirements)

- CCODP (to evaluate the performance of the QUIK design output)

- CCGEOM (to generate the blade/hub/shroud geometry in PLOT3D format for import into a CAD/CAM package).

So far I have had little luck in "chaining" the data between applications... I can get sample and test jobs to run under each application, but can't seem to get the output from one loaded into the next - in spite of the fact that the manuals all say it is possible. I also can't seem to get the CCGEOM app to output ANY PLOT3D files as listed in the manual.

Has anyone tried using this software suite, or know the proper sequence/editing/post-processing required to get data from one to the next? It looks like an inexpensive and promising solution for a hobbyist to develop small compressors with, but I've got to get it working first...

Thanks in advance!

This reminds me of the Scrap Yard constructors program (forget its real name) intended to float a fire boat across a lake and douse a fire. The team with the centrifugal compressor idea I really liked, took a drum brake hub, welded three or four radial tabs on it, and added a cover, with inlet and outlet pipes. Crude but effective.
