Friction (Rigid Body Contact)
By adding a Friction subnode to Rigid Body Contact node, you can model frictional forces and losses between the two contacting rigid bodies. There can only be one Friction subnode under a Rigid Body Contact node.
Friction
Enter a Friction coefficient μ.
Enter a Characteristic slip velocity v0. The default is mbd.diag*(1e-3[1/s]), where mbd.diag is the diagonal of the bounding box of the geometry. The characteristic slip velocity should be small compared to the actual slip velocity at the contact point. This is the velocity with which the contact surfaces slide, even under sticking conditions.
Advanced
Enter values or expressions for the:
Maximum friction force Ff,max. The default is Inf, which means that no upper limit is imposed on the friction force.
Select Compute frictional dissipation to compute and store the energy dissipated by the friction. This adds a global dependent variable with an ODE for energy integration purpose.
