Hello all! 

First, please bear with me here, as I am relatively new to PyChrono. I 
appreciate any/all feedback or tips! 

I have applied a coefficient of friction to a body (ChBodyAuxRef) imported 
from SolidWorks via the "*mat.SetFriction(fric_coefficient)"* command for a 
NSC material. This material then appears in my collision model for the 
body. 

My question is: *is it possible to have this friction coefficient only act 
in one direction?*

Basically, I am trying to model an extremely frictional material which only 
adheres to a surface when a shear load is applied in one specific 
direction. So, I need the *friction coefficient to very high in one 
direction only*. As I understand it now, the command mat.SetFriction() sets 
an *omnidirectional coefficient of friction* to the surface. 

Any ideas on if this is even doable? 

Thanks so much, 
Maddy
