Is it possible to create & import user defined bone geometry?
I have some segmented pelvis CT data & was wondering if it would be possible to use this in conjunction with OpenSim to estimate loading conditions.

Re: User defined bone geometry?
Yes, you could generate a mesh and use an ElasticFoundationForce (https://simtk.org/api_docs/opensim/api_ ... Force.html). Alternatively, you could extract the relevant geometric parameters and build a simpler model. You may find these papers helpful:
