The kernel uses offline visualization. The simulation happens as fast as possible; this means that there is no waiting time between two different discrete events. While simulating as fast as possible, the state of the factory is serialized into a file, and a simulation log is generated made out of the states.
This simulation log enables the user of the simulation tool to see and evaluate the states at a later point in time. This can be done by a browser, which can be launched by clicking here.
More information comes later.
