Hi,

I want to run a non-linear simulation analysis, with 2D simplification, but both of these options are grayed out in the Study panel (see first figure in attachment). 

I am running SolidWorks Premium 2014 X64 Edition SP 4.0 (see second figure in attachment).

How do I enable the non-linear & 2D simplification options?  Do I need an upgrade, and if so, exactly what?

Thanks, Bert
