Strangely this guy may not be a troll.
I am a mech engineer, and the majority of my day is spent driving this software (I also the resident consultant).
Pro/E has been trying to get their app to use several computers for a couple of years. They currently have a menu pick for "distrubited computing". It doesn't do any thing, but its there.
At the pro/user conf. in Orlando (1998?)they had a cluster of Sun's machines running an analysis.
Mechanica (the FEA package)is supposed to support multi-processors, but I don't have a mp box to test it on.
Hopefully they get something working soon. We have bunches of boxes doing nothing most of the day, it would be nice to run some large simulatons/animations distributed.
