I haven't tried it, but the plug-in I checked before didn't meet my requirements because it couldn't analyse other materials than solids (ie, no composite with fibres as I work with). It also had some problems to calculate pieces mounted together as on part. Dad doesn't use it at all, at his place they have a uge department only working with FEM mathematics in very complex simulators, he just gives them his solids and they return a result.
I'm waiting for the Swedish Technical Fair so I can test the new stuff and get a nice demo. And free cookies.
Cheers,
