pub type Stiffness = Qty<0, 1, -2, 0, 0, 0, 0>;Expand description
N·m⁻¹ — a spring’s k, and the penalty stiffness a contact is modelled with.
This is what sets a mechanical solver’s stability limit: a mass on a spring
oscillates with period 2π√(m/k), and an explicit integrator has to resolve that
period whether or not anyone cares about it. Stiff contact is expensive for
exactly this reason.
