physical time scale
 
How do you choose correct physical time scale?

Some options:
* Use auto time scale and let the solver work it out. Usually this is a conservative estimate, that means you can go much faster.
* Read the documentation as it has an extensive discussion on it.
* But I usually do not bother. A start with auto time scale and accelerate it as the simulation progresses using "edit run in progress" until I get a good convergence rate.
