Thanks for the reply. Now I have a better understanding on such so called forward dynamics mechanism. Following your answer I still have two questions. 1. Since the excitation is the input of muscle, and all muscles are actuators. Does it mean the Arg of function set_actuator_input() should be the e...

Beside the term "excitation" in class Muscle() in SconePy, there's also another term called "activation", is that used for MTU muscl...
