Hi, kind of stuck with how to calculate frictional forces in a particular problem: I am modeling yarn using mass spring system, zero dimensional nodes. Question is, what to do when a yarn can get stuck between a wedge?
How to calculate friction force vector, surface reaction and so? Since a node is zero dimensional, seems kind of impossible. Maybe I need to assume kind of finite dimensions and work with some kind of penalty method penalizing the distance between a node and the surfaces of the wedge? Still, I am completely stuck...
