Hi Jeffery: As far as I can recall, that is what is included with the "premium" line of that year (static analysis only). However it should also include COSMOSMotion (rigid body dynamics). You can buy something called "COSMOSWorks Professional" that includes frequency, buckling, thermal, and some other modules. You'd have to contact your reseller for that. Hope this helps. Regards, Tony.

I know that COSMOSMotion will do vibration analysis, and you have that. It is rigid body vibration (you put springs in the model). If you want elastic body vibration, that only comes with COSMOSWorks Professional.
