OMEdit Workflow

Use OMEdit to browse BobLib diagrams, inspect parameters, run manual experiments, and view animations.

Prerequisites

• A full OpenModelica installation that includes OMEdit. On Linux, omc alone is enough for CLI work but not for OMEdit.
• Modelica Standard Library 4.1.0 and VehicleInterfaces 2.0.2. See Setup.
• The BobLib repository on a local path without unusual permissions.

Platform	Notes
Linux	Install the full OpenModelica package set from the official repository. Qt needs desktop X11 or Wayland integration.
Windows	Use the standard OpenModelica installer.
macOS	Native packages are limited. Use the official macOS notes, a Linux or Windows host, or a VM.

Open BobLib

1. Start OMEdit with no BobLib package loaded.

2. Open the File menu with Alt+F. Press Down until Open Model/Library File(s) is highlighted, then press Enter.

   

3. In the file chooser, select BobLib/package.mo and open it.

   

4. In the Libraries browser, expand BobLib > Experiments > Standards.

5. Open VehicleSim or FourPostSim.

   

If OMEdit reports a missing Modelica or VehicleInterfaces package, install the missing library, restart OMEdit, and load BobLib/package.mo again.

Run a simulation

1. Set a scratch working directory in Tools > Options > General, for example /tmp/BobLibOMEdit.

2. Open VehicleSim or FourPostSim as above.

3. Click Check Model for a quick sanity check.

4. Open Simulation Setup from the model toolbar. Review the start and stop time, interval, solver, tolerance, output format, and simulation flags. If the toolbar is hidden, use View > Toolbars > Simulation Toolbar.

   

   

5. Click Simulate.

6. Inspect variables in the Plotting perspective after the run finishes.

OMEdit writes each run to a model-named subdirectory of its working directory. That directory holds the translated model, executable, initialization XML, logs, and results. If a run behaves unexpectedly, delete that directory and simulate again.

Animation

The standard models open with MultiBody animation on (headless = false). Set headless = true to run without visualization geometry. See Entry Points.
