Creating acoustic interface sections

Acoustic interface sections are used to define the section properties of two-dimensional, three-dimensional, and axisymmetric regions that model an acoustic medium undergoing small pressure changes. You use acoustic interface sections when you want to couple the acoustic medium to a structural model. For more information, see Acoustic interface elements.

  1. From the main menu bar, select SectionCreate.

    A Create Section dialog box appears.

    Tip: You can also click Create in the Section Manager or select the create section tool in the Property module toolbox.

  2. Enter a section name. For more information on naming objects, see Using basic dialog box components.

  3. Select Other as the section Category and Acoustic interface as the section Type, and click Continue.

    The section editor appears.

  4. Select an acoustic medium material for the acoustic interface section. If desired, click to create a material; see Creating or editing a material, for more information.

  5. Enter a value for the section Plane stress/strain thickness. If the section will be used with a two-dimensional region, you must specify the section thickness. Abaqus/CAE ignores the thickness information if it is not needed for the region type.

  6. Click OK to save your changes and to close the section editor.
