Linear (velocity dependent) damper
Linear damper acting as line force between frame_a and frame_b. A force f is exerted on the origin of frame_b and with opposite sign on the origin of frame_a along the line from the origin of frame_a to the origin of frame_b according to the equation:
f = d*der(s);
where "d" is a parameter, "s" is the distance between the origin of frame_a and the origin of frame_b and der(s) is the time derivative of "s".
In the following figure a typical animation is shown where a mass is hanging on a damper.
|frame_a||Frame_a||Coordinate system fixed to the force element with one cut-force and cut-torque|
|frame_b||Frame_b||Coordinate system fixed to the force element with one cut-force and cut-torque|
|s_small||Position||1e-06||Prevent zero-division if relative distance s=0|
|animation||Boolean||true||= true, if animation shall be enabled|
|length_a||Distance||world.defaultForceLength||Length of cylinder at frame_a side|
