What algorithm does OpenSim use for contact detection and force calculation? Any sources? I can't find this in the manuals.

Hi Anne,

OpenSim contact exposes the functionality available in Simbody/SimTK
https://simtk.org/docman/?group_id=47.
The doxygen documentation, user manual there as well as the Simbody user forum will better serve you in this regard.

Good luck and please let us know if you don't find answers there or post pointers on this forum for the benefit of other users who may have similar questions.

Good luck,
-Ayman

There wasn't anything on the elastic foundation model.

Hi Anne,

Please consult section 5 and the appendix in the paper (link below)

This is very helpful. However, how is this part done:

"For each of these triangles, the point S on body B’s surface closest to the centroid is determined"
