Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

The 3 signals of the force connector are interpreted as the x-, y- and z-coordinates of a force acting at the frame connector to which this component is attached. Via parameter resolveInFrame it is defined, in which frame these coordinates shall be resolved:

Types.ResolveInFrameB.Meaning
world Resolve input force in world frame (= default)
frame_b Resolve input force in frame_b
frame_resolve Resolve input force in frame_resolve (frame_resolve must be connected)

If resolveInFrame = Types.ResolveInFrameB.frame_resolve, the force coordinates are with respect to the frame, that is connected to frame_resolve.

If resolveInFrame is not Types.ResolveInFrameB.frame_resolve, then the position vector and the orientation object of frame_resolve must be set to constant values from the outside in order that the model remains balanced (these constant values are ignored).
