As soon as an experiment is launched, the modeler is facing a new environment (with different menus and views) called the Simulation Perspective). The Navigator is still opened in this perspective, though, and it is still possible to edit models in it, but it is considered as good practice to use each perspective for what is has been designed for. Switching perspectives is easy. The small button in the top-left corner of the window allows to switch back and forth the two perspectives.
The actual contents of the simulation perspective will depend on the experiment being run and the outputs it defines. The next sections will present the most common ones (inspectors, monitors and displays), as well as the views that are not defined in outputs, like the Parameters or Errors view. An overview of the menus and commands specific to the simulation perspective is also available.
