By default, SolidWorks Simulation does not open when SolidWorks does. We can change this by going to Tools > Add-Ins, shown in Figure 5.

Figure 5. How to start Simulation SolidWorks .

The Add-Ins window, replicated in Figure 6, pops up. Check the box to the left of “SolidWorks Simulation” to enable Simulation in this instance of SolidWorks. If you want Simulation to be enabled every time you start SolidWorks, check the box to the right of “SolidWorks Simulation” as well. If this is your first time using Simulation, you may be asked to agree to an end-user license agreement.
