Measures the relative speed v of a flange in an ideal way and provides the result as output signals (to be further processed with blocks of the Modelica.Blocks library).
Description: (left) driving flange (flange axis directed in to cut plane, e. g. from left to right)
Description: (right) driven flange (flange axis directed out of cut plane)
Description: Relative velocity between two flanges (= der(flange_b.s) - der(flange_a.s)) as output signal
