# SCONE Models

SCONE is designed to work with OpenSim for modeling and simulation. The only requirement is that the model has controllable actuators, such as hill-type muscletendon units or torque-based actuators. If you want the model to interact with the environment (which is typically the case), the model also needs to contain collision shapes and contact models. This is needed to compute the reaction forces during the forward dynamics simulation.

For models in predictive simulations counts: the simpler the better. This is both because having simpler models require less actuators and less parameters to optimize. In addition, the simulation performance of OpenSim models increases with model complexity, so optimizations will be much quicker with simpler models.
