What we have done here is to give BicepsLong a new and more advanced muscle model. Let's have a look at
the consequences. Press the M<-S button or F7 and subsequently run the InverseDynamicAnalysis. Then,
open a new ChartFX window to investigate the results.
This graph shows the muscle force or more precisely the force in the tendon. The force in this more complex
muscle model is composed of two elements: The active part coming from the contractile element of the
muscle, and the passive part due to the stretching of the parallel-elastic part of the muscle. The two parts
come together in the tendon force, Ft. The parallel-elastic part of the muscle is represented by Fp in the
result tree. If you pick this property, you should get the following graph:
