Specify a Torque Controller

You can add a Torque Controller can be added to a Geometry. This creates a torque on the Geometry which will react to the forces acting on the Geometries from the contacts with particles. Torque Controllers can be used to allow the Geometry to move based on gravity.

To specify a Torque Controller:
  1. In the Creator Tree, right-click an existing Geometry and then select Add Motion.
  2. Select Add Torque Controller.
    Optionally, click the icon.
  3. Rename the Torque Controller as appropriate and specify the following details:
    For Specify
    Torque Controller
    Specification Start Time

    Specify the point in the simulation at which the motion will begin.
    End Time

    Specify the point in the simulation at which the motion will end.
    Select the Loop Every checkbox to enable the kinematic to be looped. For example, a kinematic with the Start time of Xs and End time of Ys with Loop Every set to Zs would run from Xs to Ys, and then repeat again at (X+Z)s to (Y+Z)s and again at (X+2Z)s to (Y+2Z)s until the specified Until Time is reached.
    Until Time

    Specify the time until when the kinematic will be looped.
    Torque Equations

    Set an equation for the torque. This can be a single value or an equation for more advanced behavior.
    Initial Angular Velocity
    Select the Include Gravity in Torque Calculation checkbox to add a gravity force to the object. This is based on the mass of the section (and can be changed in the Mass section).
    Select a Damping Coefficient value from the Damping Coefficient list. Damping is calculated by CωI where C - Damping coefficient, I - Moment of Inertia of the object and ω is the angular velocity of the object.
    Select the Constrain Motion Directions checkbox to constrain the motion in 1 or 2 dimensions. These dimensions are defined as a vector in the X, Y, and Z direction.

    Axis 1 and/or Axis 2 to constrain the motion in the directions the Geometries will be able to move.
    Select 1D or 2D to constrain the Geometry in one or two dimensions.
    Select Enable Angular Speed Cap to specify the maximum angular speed value.
    Select the maximum angular Speed Cap value from the Angular Speed Cap list to constrain the motion. You can constrain the motion in 1 dimension. This axis is defined by a vector defined by X, Y, and Z components. The amount of displacement can be capped in both directions by selecting the box and specifying high and low values for the Angular displacements.
    Reference Space

    Select the Local or Global option to base the motion on the specific Geometry or the EDEM domain.
    Point of Action Select Use Start Point to specify the point of action (the center of the rotation) and if the geometry section is rotating about the start point of the Torque Controller.

    Specify the X value to define the point of action in the X direction.
    Select Use Manual Point to define a specific point.

    Specify the Y value to define the point of action in the Y direction.
    Select Use Center of Mass if the torque applies to the Center of Mass of the object.

    Specify the Z value to value to define the point of action in the Z direction.
