Is windchill capable of managing NX/CAE Data? (*.prt, _i.prt, *.fem, *.sim)

Curious if anyone out there (1) manages NX CAD data via Windchill and if so (2) if Windchill is able to manage NX's CAE Data?  In particular, the relationships between the files:  *.prt  ->  *_i.prt  ->  *.fem  ->  *.sim

Also, if you manage NX Data, what has been your exerience and/or lessons learned?  Any help will be greatly appreciated.  Thanks in advance!
