Hi Tenson, Irving2008

The software is called Catia V5 made by Dassault. It is a very powerful piece of software designed for high end use, and very expensive. FEA is just one small part of the software.

I'm sure there are cheaper packages out there which will do the FEA part of the job - on simple parts at least.

It will also do modal analysis although I've not used it for that.
