On the Home ribbon in the Simulation group, click New Simulation to create a new instance of the default simulation type. The default simulation type is shown in the tooltip.

To create a different simulation type and set the default simulation type, on the Home ribbon in the Simulation group, click the drop-down arrow next to the New Simulation button and choose the simulation type to create. To change the default simulation type for future Analyst sessions, click the top menu item to set the current simulation type as the default.

In the Navigator, choose New Simulation from the Simulations node context menu and then the desired simulation type from the context menu.

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