Hi,

Does someone can clarify me on how to implement the HuntCrossley in C++ contact model ?

It is similar to ElasticFoundationForce, but without assigning the mesh?

Thanks

Joana

Hi Joana
I have the same problem, if you have solved your problem, it would be great if you could update this post.
Thanks

Hi!

To create the geometrys to the Hunt Crossley model you have to do this:

First you creat an halfspace:


ContactHalfSpace floor(Vec3 location, Vec3 orientation, ground, "ground");
osimModel.updContactGeometrySet().append(&floor1);

Then you create a sphere geometry

OpenSim::ContactGeometry* sphere;
sphere = new ContactSphere(radius, Vec3 location, *block, "block");
osimModel.updContactGeometrySet().append(sphere);

Hope this will help!

Thanks Joana
It was really helpful. just two more questions:
1- How should I specify contact parameters? Such as stiffness of contact bodies, friction coefficients etc.
2- If I want to use "elastic foundation force", should I define a half space again?
