Information

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

The absolute angular velocity of frame_a with respect to the world frame is determined and provided at the output signal connector w.

Via parameter resolveInFrame it is defined, in which frame the angular velocity is resolved:

resolveInFrame =
Types.ResolveInFrameA.
Meaning
world Resolve vector in world frame
frame_a Resolve vector in frame_a
frame_resolve Resolve vector in frame_resolve

If resolveInFrame = Types.ResolveInFrameA.frame_resolve, the conditional connector "frame_resolve" is enabled and w is resolved in the frame, to which frame_resolve is connected. Note, if this connector is enabled, it must be connected.

Example

If resolveInFrame = Types.ResolveInFrameA.frame_a, the output vector is computed as:

w = MultiBody.Frames.angularVelocity2(frame_a.R);
