Introduction

• Events in Modelica:
  • rich set of event related features
  • additional synchronous elements
  • event semantics quite involved, sometimes counterintuitive
  • "Modelica [...] provides only very limited means for the description of such [i.e. structurally changing] models" [Zimmer 2007]
• Using components and graphical tools:
  • large library (MSL) mostly for physical modelling
  • contains some event-related blocks
  • build new components with explicit Modelica code
• Modelica implementations:
  • contain different subsets of the MSL
  • differ subtly in event behaviour
  • used here: Dymola and MapleSim
