	Thanks for the tip.  You didn't say whether that was a free download or
not (I've seen similar programs offered for several thousand dollars)
but will take a look at it.  If you're looking into finite element
analysis you're way, way beyond me!  I work with a bunch of aircraft
design people who use such techniques for almost all of their
calculations, and also some electromagnetics guys who use similar
techniques for predicting RF properties of materials.  Sounds a little
bit beyond what the average TC nut needs!
