Using Simulation Studio
Simulation Studio let's you easily create and run simulations. To start using it, you have to create new Project.
Figure 1.: Creating new Project.
You'll be able to access the creation popup by clicking on the "Create Project" button in the Projects list page (click on "...show all" link in the left sidebar).
Make sure to select trained simulator model from the list of available models. If you don't have any trained models, you can train one in the Model Engineer's Environments or use one of publicly accessible ones (should be available in the same list already).
