This tutorial is intended as a first introduction to DynRisk. You will start from scratch and create a very simple model. The tutorial takes you through many DynRisk features without spending too much time on details or the theory underlying these features. For a complete description of menus, commands, operators, functions etc., we refer to the DynRisk User Documentation. You will learn about the following: • Starting DynRisk • Creating nodes • Editing nodes • Editing in graphical view • Linking nodes • Specifying uncertainty • Editing edges • Saving a model • Testing a model • Performing a simulation • The result file • Creating plots We begin by starting DynRisk. As soon as the “splash screen” is gone you should see an empty window. At the top of the screen you'll see the usual menu bar, and below it a toolbar.
