Directional (anisotropic) friction support in Chrono
Harrison Pearl
Hi All,
Does Chrono support directional (anisotropic) friction, where friction varies based on the direction of motion relative to the surface?
if it doesn't, one approach I’m considering is to use as a work around is the rolling friction feature. By applying it conditionally based on the velocity vector of an object relative to the surface with directional friction, I think this would constitute, for my purposes, anisotropic friction.
Would this be a reasonable way to approximate anisotropic friction in Chrono, or are there better methods or workarounds?
Sincerely,
Harrison Pearl

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.
Sincerely,
Harrison Pearl

Harrison,
A contact container includes all contacts between contactables (i.e., physics objects that carry collision geometry). Assuming you followed the example Luning pointed to, you dealt with contacts between two ChBody objects. You would do the exact same thing if one or both bodies were of type ChBodyAuxRef (the only difference is the local reference frame with respect to which the collision model is positioned (centroidal frame for a ChBody, some other frame for ChBodyAuxRef).
