Have you gone through the tutorials? I presume you are talking about SW Simulation Professional, correct?
For your information, I don't have solidworks simulation. I have only solidworks professional 2016. Can be simulate the model with SIlodworks professional.
Solidworks Professıonal does not have simulation tools. SW pro has a limited version of simulation tools as Simulation Express.
But it is a limited version. It just run for one body, you can not simulate assembly.
If you combine all the body as a one body , you can simulate it in Simulation Express.
