Specify a Rotation

Rotations move the Geometry about a user-defined point with a specified angular speed and acceleration.

To specify a Rotation:
  1. In the Creator Tree, right-click an existing Geometry and then select Add Motion.
  2. Select Linear Rotation Kinematic or Sinusoidal Rotation Kinematic (used to model oscillating motion).
    Optionally, click the or the icons.
  3. Rename the kinematic as appropriate and specify the following details:
    For Specify
    Linear Rotation Kinematic
    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 Start time of Xs and End time of Ys with Loop Every set to Zs would run from Xs to Ys 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.
    Initial Velocity

    Specify the speed of the section at the specified start time.
    Acceleration

    Specify the acceleration. You can set the acceleration to 0.
    Reference Space

    Select Local for the values to be based on the origin of the imported CAD Geometry, this will depend how the CAD file is drawn.

    Select Global for the values to be based on the EDEM origin.
    Select the Moves with Body checkbox to update the center as the section moves to ensure that the center of rotation remains in the same relative position to the Geometry section.
    Axis of Rotation

    Specify the X, Y, and Z values for the values for the Start and End point of the axis used for the rotation of the object. .
    Select the Display Vector checkbox to display the vector used for the rotation to verify that the object will move in the correct direction.
    Point of Action

    Specify the point of action which is the center of rotation.
    Sinusoidal Rotation Kinematic
    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 start time of Xs and end time of Ys with Loop Every set to Zs would run from Xs to Ys 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.
    Frequency

    Specify the frequency of the oscillation.
    Offset

    Specify the oscillation offset. For example, if you set two sections with identical oscillations offset by 180°, they will travel in opposite directions.
    Displacement Magnitude

    Specify the amplitude of the oscillation in each direction.
    Reference Space

    Select Local for the values to be based on the origin of the imported CAD Geometry, this will depend how the CAD file is drawn.

    Select Global for the values to be based on the EDEM origin.
    Select the Moves with Body checkbox to update the center as the section moves to ensure that the center of rotation remains in the same relative position to the Geometry section.
    Axis of Rotation

    Specify the X, Y, and Z values for the Specify the X,Y and Z values for the Start and End point of the axis used for the rotation of the object.
    Point of Action

    Specify the point of action which is the center of rotation.
