TypeModel data

LevelPartPart instanceAssembly

Abaqus/CAEProperty module; supported for two-dimensional, three-dimensional, and axisymmetric acoustic interface elements. Contact elements are not supported.

Required parameters

ELSET

Set this parameter equal to the name of the element set containing the ITT-, ISL-, IRS-, and ASI-type contact elements for which properties are being defined.

Optional parameters

NAME

Set this parameter equal to a label that will be used to refer to this interface definition. The label given can be used to identify this particular interface definition in user subroutines such as GAPCON.

Data line for ITT-type elements

First (and only) line

  1. Radial clearance between the pipes.

There are no data lines for ISL21A and ISL22A elements

 

There are no data lines for IRS-type elements for use with axisymmetric elements

 

Data line for ASI1 elements

First (and only) line

  1. Area associated with the elements.

  2. Enter the direction cosine, in terms of the global Cartesian coordinate system, of the interface normal that points into the acoustic fluid:

  3. X-direction cosine.

  4. Y-direction cosine.

  5. Z-direction cosine.

Data line for ASI-type elements for use with 2D elements

First (and only) line

  1. Element thickness. The default is unit thickness.

There are no data lines for ASI-type elements for use with axisymmetric elements or 3D elements
