A flange is described by the connector class Flange_a or Flange_b. As already noted in section Overview, the two connector classes are completely identical. There is only a difference in the icons, in order to easier identify a flange variable in a diagram. Both connector classes contain the following variables:
SI.Angle phi "Absolute rotation angle of flange"; flow SI.Torque tau "Cut torque in the flange";
If needed, the angular velocity w and the
angular acceleration a of a flange connector can be
determined by differentiation of the flange angle phi:
w = der(phi); a = der(w);
