This can prove useful if you use components from more than one package when designing a model. To view the contents of a package as a separate group within the Class Browser, rightclick its name and choose View as Group.
Figure 2-3: Browsing the Modelica Standard Library in the Class Browser.Ħ Chapter 2: Introduction 9 Clicking the symbol to the left of an expanded package will show it as collapsed again, hiding its contents. As seen in the figure below, the Modelica Standard Library is hierarchically organized with several levels of subpackages. To show the contents of a package, for instance the Modelica package, expand it by clicking the symbol to the left of its icon.
Packages are represented as branches of the tree and components as leaves. The Class Browser uses a tree view to visualize the contents of a library. This library is loaded when the Model Center is started and can be browsed using the Class Browser, visible on the left-hand side of the Model Center. Model Center starts with a default configuration, but allows for customization.ĥ 8 Chapter 2: Introduction 2.2 The Modelica Standard Library SystemModeler is delivered with a subset of the Modelica Standard Library, a brief overview of which is given here.
The menus, tool buttons, and windows available in Model Center depend on the installed version. If you would like to configure the link, see Section 1.4 on page 3 for details. If you do not have Mathematica, you can safely skip this step by clicking the Cancel button. If it does not succeed, a dialog for configuring the link is shown. When the Model Center is started for the first time, SystemModeler tries to configure SystemModeler Link for Mathematica. A splash screen will appear while the model editor is loading. Choose Wolfram SystemModeler Wolfram SystemModeler from the Start menu in Windows.
2.1 How to Start SystemModeler SystemModeler consists of a modeling environment, Model Center a simulation environment, Simulation Center and the Wolfram SystemModeler Link package for Mathematica that connects to SystemModeler How to Start the Model Center The natural starting point of SystemModeler is the Model Center. The Getting Started document found in the Help menu of Model Center and Simulation Center contains several examples that are useful for getting familiar with modeling in SystemModeler.
At the end of this chapter we will also introduce the Mathematica notebook environment and show how SystemModeler integrates into Mathematica. You will learn how to use Model Center to build your own model with components from the Modelica Standard Library as well as how to simulate the model and plot variables using Simulation Center. 1 Wolfram SystemModeler User Guide IntroductionĢ Chapter 2: Introduction 5 Chapter 2: Introduction This chapter gives a short introduction to SystemModeler.
