On the Home ribbon in the Simulation group, click New Simulation to create a new instance of the selected simulation type.

To change the selected simulation type, on the Home ribbon in the Simulation group, click the drop-down button next to the displayed simulator and choose a simulator. Click Make Default to set the chosen simulator as the default simulation type for future Analyst sessions.

In the Navigator, choose New Simulation from the Simulations node context menu and then the desired simulation type from the context menu. If you have created geometry for your model, only the simulators specific to the dimensionality of your geometry will be enabled.

A node for the new simulation displays under the Simulations node in the Navigator and a corresponding Simulation view is created.
