Hi,
Following up, I was able to successfully create and implement a custom friction model based on the provided demo you linked. The model works as expected when applied to a ChContactContainer object. Is it possible to apply this custom friction model to an object of type ChBodyAuxRef, or is there a different approach I should take? Any assistance or insights would be greatly appreciated.
