Hi jason, I have at present written down the following models:
1. Linear hooke contact model 2. Non linear hertz model 3. Linear Kelvin-Voigt Contact Model 4. Nonlinear Hunt and Crossley Contact Model 5. Nonlinear Hunt and Crossley Contact Model 6. Nonlinear Flores et al. Contact Model 7. multi_mass_spring_damper() <https://pydy.readthedocs.io/en/stable/models.html#pydy.models.multi_mass_spring_damper> 8. n_link_pendulum_on_cart() <https://pydy.readthedocs.io/en/stable/models.html#pydy.models.n_link_pendulum_on_cart> 7 and 8 are taken from pydy, are they non trivial cases? Also could you suggest any resources for muscle force, actuator force and aerodynamic force models which are useful for the user? I have taken 1 to 6 from the here https://www.researchgate.net/publication/299604992_Contact_Force_Models_for_Multibody_Dynamics, are they useful cases?
