Rotational Damper
Purpose
Ideal viscous rotational damper

Description
The Rotational Damper models an ideal linear damper in a rotational system described with the following equations:
\[\tau = -D \cdot \omega\]
where \(\tau\) is the torque flow from the unmarked towards the marked flange and \(\omega\) is the angular speed of the marked flange with respect to the unmarked one.
Parameters
- Damper constant
The damping (viscous friction) constant \(D\), in \((\frac{\mathrm{Nms}}{\mathrm{rad}})\).
- Initial displacement
The initial displacement of the flanges, in radians. May be specified in order to provide proper initial conditions if absolute angles are measured anywhere in the system. Otherwise, this parameter can be left blank.
