Description
This goal requires the average speed of the system to match a desired average speed.
The average speed of the system is the displacement of the system's center of mass divided by the duration of the phase.
- Examples:
- example2DWalking.cpp.

Perform any caching before the problem is solved.
You must override this function and invoke setNumIntegralsAndOutputs().
- Precondition(s):
- The model is initialized (initSystem()) and getModel() is available. The passed-in model is equivalent to getModel(). Use this opportunity to check for errors in user input.
