Hands-On Seminar

Seeing is believing – Visualize and communicate your results!

Creative usage of the 3D view in SimulationX improves your knowledge of a model’s structure and your understanding of the simulation results making your presentation the more convincing! Join our project engineers when they demonstrate the possibilities and how you can use control elements, indicators and animated icons in the diagram view.

  • Get tips and tricks first-hand on how to use the 3D view, control elements, indicators and diagrams.
  • Learn how to make the most of the Modelica annotation for animated icons.



  • View your simulation results in a comprehensible fashion
  • Identify simulation errors at an early stage with the help of visualizations
  • Communicate your results to management and customers
  • Recommended for: Engineers who build their own models or libraries
  • Duration: 1,5h
  • Slot/location: 11 - 12 AM, room St. Petersburg
  • Session leader: Alex Magdanz, Thomas Neidhold
