Your Simulation is a standalone license and not attached to a seat of SolidWorks Premium? You might want to check that, first.
If that's the case, then you would need to modify your install to include that. It would probably be listed under 'Addition Product Licenses' when you start the install. If you don't have the DVDs, and you're on subscription, you can just go to the SolidWorks website and download the files.
If, however, it's simulation attached to a seat of SolidWorks Premium then Tools->Addins->Simulation
simulation is simulation is simulation...there are no separate installs other than for geostar/cosmosm
most likely you need to go to your license manager and set the license order to put simulation premium above swx prem, swx prem you only get static
Nice. Worked like a charm.
