A simulation can have any of the following states:
Initialized: The linked simulation models have been loaded and all necessary data is transferred. At this stage, the simulation is ready to start.
Running: The simulation is in progress, that is, the control flow is running step by step, with or without animation.
Paused: The simulation has been paused at a certain stage.
Stopped: The simulation was stopped. There are no linked simulation models loaded and the simulation execution is not active.
