Hi,
I have a question about FEBio's capability of modeling a planar joint between two rigid bodies.
I'm trying to build a model for a knee simulator machine, and the loading parts of the which are considered 2 rigid bodies. (Simply call one is tibia holder plate, the other is a loading cylinder.) I want to constrain all DOFs of the loading cylinder except the superior-inferior translation, where the load applies. And the tibia holder plate can only be free in superior inferior translation, medial-lateral translation, and varus-valgus rotation, and is pushed by the loading cylinder always.
To model this, I want to create a "planar joint" (allows both translation and rotation) to connect the 2 rigid bodies. However, I can only find a "rigid joint" in "contact" menu that can connect 2 rigid bodies, and the rigid joint can be only spherical joint for now (if I understand it correctly?).
My question would be, if FEBio is able to create a joint that connects 2 rigid body both translational and rotational? Or some other alternatives to help me model this knee simulator machine parts?
Your help is greatly appreciated.
