If we change the femur and tibia geometry files,
will the contact point between femur and tibia be affected? How is the contact point determined?

Can we use contact geometry set to specify the contact point?

Kang,

The geometry vtp files are used only for visualization. No contact is detected/modeled in our example models.

It is possible to define a new model where contact between surfaces is detected and is used to compute/apply forces. For this you need to use .obj files to specify the geometric meshes(please check the OpenSim API example under the sdk folder of the distribution) for an example.

Hope this helps,
