+This example demonstrates at hand of a double pendulum, +how non-standard initialization can be defined: +The absolute position of the pendulum tip, and its absolute speed +shall be initially defined. This can be performed with the +Joints.FreeMotionScalarInit +joint that allows to initialize individual elements of its relative vectors. +In this case, the x-, and y-coordinates of the relative position vector +(visualized by the yellow arrow in the figure below) and of its +derivative shall have a defined value at initial time. +The configuration of the double pendulum at the initial time is +shown below, where the tip position is required to have the coordinates +x=0.7, y=0.3. +

+

+Setting only the tip's start position results in an ambiguous initialization since +two valid solutions for revolute1.phi and revolute2.phi exist. +Moreover, the calculated angles revolute1.phi and revolute2.phi +can be a multiple of expected solution phi1 and phi2, +

+ +

+To clearly indicate the preferred solution, guess initial angles can be additionally given. +In this example, it is simply done by revolute2.phi.start = Modelica.Constants.pi/2. +

-This example demonstrates at hand of a double pendulum, -how non-standard initialization can be defined: -The absolute position of the pendulum tip, and its absolute speed -shall be initially defined. This can be performed with the -Joints.FreeMotionScalarInit -joint that allows to initialize individual elements of its relative vectors. -In this case, the x-, and y-coordinates of the relative position vector -(visualized by the yellow arrow in the figure below) and of its -derivative shall have a defined value at initial time. -The configuration of the double pendulum at the initial time is -shown below, where the tip position is required to have the coordinates -x=0.7, y=0.3. -

-

-Setting only the tip's start position results in an ambiguous initialization since -two valid solutions for revolute1.phi and revolute2.phi exist. -Moreover, the calculated angles revolute1.phi and revolute2.phi -can be a multiple of expected solution phi1 and phi2, -

-
    -
  • revolute1.phi(k1) = phi1 + 2 π k1,
    • -
  • revolute2.phi(k2) = phi2 + 2 π k2.
    • -
-

-To clearly indicate the preferred solution, guess initial angles can be additionally given. -In this example, it is simply done by revolute2.phi.start = Modelica.Constants.pi/2. -
