Description

The Quadratic Speed Dependent Force component generates a force at the flange that is linearly dependent on the speed of the flange.

The boolean parameter Force Direction determines whether the force is the same direction regardless the direction of motion.

The Use Support Flange boolean parameter enables a support flange on the housing. When true (checked) the support flange must be connected in the drawing. When false the component is internally fixed to ground.
