Jason, Regarding the implementation, do you suggest similar to pydy engine? So we also need to create a System <https://pydy.readthedocs.io/en/stable/system.html> class similar to the one pydy has? Also could you suggest any sources for some trivial cases of muscle force, actuator force and aerodynamic force models, could you provide feedback on whether the model specified in my previous mail are useful or not, so that i can include them in my proposal.
