Re: [PSUBS-MAILIST] FEA
Finite Element Analysis.
A virtual model of an object is "built" in a computer and the program
breaks it down into a finite number (but very large number) of pieces
(elements) which have the applied material properties and interact with
their neighbours. An operator then applies a load and (mostly pressure in
this case) the program will spit out the stress that each area of the model
in under.
The reality of the answer relies on the way the model is built up, the
correct placement and magnitude of the applied loads by the operator. You
can get orders of magnitude difference between answers by slightly changing
the applied loads and the method of model construction.

Please forgive my ignorance, but what is FEA as refered in this message?
Thanks

You rock. Thanks for the rendering, that is cool.
A detailed 2D drawing would be great. It is Cosmos
FEA that is really giving me the headaches. I have
to rebuild all of the hull as a series of swept
features to run the FEA. Not a huge deal, but I have
been insanely pressed for time. I am working on it,
though. I think this hull has the potential to give
you high speed, if you want it. Hey, Pierre, you
have any luck with FEA on this?
