Linear 1D rotational damper
Library
Mechanics/Rotational/Components
Description
Linear, velocity dependent damper element. It can be either connected between an inertia or gear and the housing (component Fixed), or between two inertia/gear elements.
See also the discussion State Selection in the User's Guide of the Rotational library.
