Hi all;

To define a HuntCrossleyForce, we have to first define a contact sphere on a body by indicating its radius, location and orientation.I was wondering what does orientation of contact sphere mean?
Cheers,

Hi Sina,

You can leave this out or set it to 0., 0., 0. (which is the default I believe). Orientation wouldn't make sense for a full contact sphere but it does for other objects (e.g. HalfSpace, or partial Spheres if we support them etc.)

Sorry about the confusion,
