Managing Simulation Options Using the Simulation Options Dialog Box

When playing the animation, you can set simulation options using the Simulation Options dialog box. The settings are stored between sessions.

Tip: For handling of simulation results, for example, 3D animation, you can also set general options. To specify such options, select Me > Preferences > App Preferences > 3D Modeling > Systems Modeling and Execution > Dymola Behavior Modeling , the Results tab. For more information, see Native Apps Preferences Guide: Results.

Before you begin:

Simulate, or simulate and replay the animation.

Important: To display the the Simulation Options dialog box, animation must be started. It may be started automatically after simulation, depending on the value of the preference Start animation after simulation. If the Simulation Options dialog box is not displayed, you can start animation by replaying the simulation. For more information on preferences, see the tip above.

  1. If the Simulation Options dialog box does not appear, click the icon to the right in the tab to display it.
  2. In the Simulation Options dialog box, set your preferences for the animation:

    You might have to click the icon to the right in the tab to display the dialog box.

    The settings are stored between sessions.

    1. Activate Real time if you want the simulation to be synchronized with real time.

      If real time is not activated, simulation runs as fast as possible.

      The graphics update is synchronized with real time. This option slows down the simulation speed if it is faster than real time, so the animation becomes real time.

      By default, this option is not activated.

    2. If you have selected Real time, you can enter a Speed factor.

      The value 1 means that the animation is running at the same speed as the real time simulation.

      1. If you want a slower animation, set the Speed factor to a value higher than one. For example, enter 2 to animate at half speed (you display 1 second of real time simulation in 2 seconds of animation).
      2. If you want a faster animation, set the Speed factor to a value lower than 1 (but positive). For example, enter 0.5 to animate at double speed (you display 1 second of real time in 0.5 second of animation).

      By default, the speed factor is 1.

    3. If you have selected Real time and have entered a Speed factor that is (much) higher than 1, you see "jumps" in the animation. Select Adapt step size to have a smoother animation.

      By default, this option is selected.

    4. If your model contains 3D shapes from Modelica libraries, activate Display Modelica Shapes to see them displayed.

      By default, this option is activated.

      Tips:
      • You can select when to start animation automatically after simulation. By default, animation starts automatically after simulation when you have any 3D shape in the model. For finding this option, see the Tip in the introduction above.
      • If you need to adapt Modelica arrows produced by, for example, force and torque measurements, to the scale of the model you visualize, you can use the Arrow length factor option to set the scaling factor. For finding this option, see the Tip in the introduction above.

    5. If your model contains 3D shapes from the CATIA library (for example glyphs) activate Display CATIA Library Shapes to see them displayed.

      You can use this option for old models that use the CATIA library. For new models, prefer mapping of logical and physical models. See Functional & Logical Design User's Guide: Mapping of Logical and Physical Models.

      By default, this option is not activated.

      Tip: By default, animation starts automatically after simulation when you have any 3D shape in the model. You can change this by an option. For finding this option, see the Tip in the introduction above.

    6. To display monitored variables on the diagram, activate Display Pinned Variables.

      By default, this option is activated.
