Contact Ellipsoid in Simbody but not Opensim?
Posted: Mon Sep 13, 2021 7:27 am
Hello,
I am trying to implement ellipsoids in a hunt-crossley contact model. This is said to be possible in the Sherman 2011 paper.
Looking at the opensim doxygen there is no option for contact ellipsoid: https://simtk.org/api_docs/opensim/api_ ... metry.html

However, there is an option looking at the doxygen for simbody: https://simtk.org/api_docs/molmodel/api ... metry.html
![Image](https://simtk.org/api_docs/molmodel/api_docs22/Simbody/html/classSimTK_1_1ContactGeometry.png)
Why are ellipsoids not available in OpenSim?
Thanks for your help,
Evan
