Support Selection
  1. From the Loads section of the action bar, click Applied Translational Acceleration .
  2. Optional: Enter a descriptive Name.
  3. Select the geometry supports in the model.

    You can apply the translation acceleration to a displacement restraint created as a secondary base in a frequency step. Select Sim feature as the type of support, then select the appropriate displacement restraint from the window that appears.

  4. Enter the Translation magnitude.
  5. Select a Degree of Freedom representing the direction of the acceleration within the selected axis system.
  6. Optional: Enter a Scale factor that is applied to the magnitude in each step.
  7. Select an Amplitude that defines the magnitude during the step.
  8. Optional: For harmonic response steps, specify the Phase angle for the amplitude curve. The phase angle determine the real (in-phase) and imaginary (out-of-phase) parts of the magnitude. A phase angle of 0ยบ indicates a value with no imaginary component.
  9. Click OK.
