Defining an inward volume acceleration

You can create an inward volume acceleration load to specify a volume acceleration at a vertex or node on the boundary of an acoustic medium. (For more information, see “Loads,” in Acoustic, shock, and coupled acoustic-structural analysis.)

  1. Display the inward volume acceleration load editor using one of the following methods:

  2. Click the arrow to the right of the Distribution field, and select the option of your choice from the list that appears:

    • Select Uniform to define a load that is uniform over the region.

    • Select an analytical field to define a spatially varying load. Only analytical fields that are valid for this load type are displayed in the selection list. Alternatively, you can click to create a new analytical field. (See The Analytical Field toolset,” for more information.)

  3. In the Magnitude field, enter the volume acceleration (units L3T−2).

  4. If desired, click the arrow to the right of the Amplitude field, and select the amplitude of your choice from the list that appears. Alternatively, you can click to create a new amplitude. (See The Amplitude toolset,” for more information.)

  5. Click OK to save your data and to exit the editor.
