Ghosts are read-only information holders.
Connectors can be drawn from them, but not into them. Ghosts can also be used to create control panels, which will be useful in future exercises. By placing a set of ghosted variables in a single location on the diagram, you can easily manipulate parameter values as you interact and run simulations of the models. Simulation Run Model 2.1. After Model 2 is completed and tested, the first simulation run will compare how pool temperature changes over time based upon the initial temperature of the water in the pool.
