*SURFACE
18.46 *SURFACE: Define a surface or region in a model.
This option is used to define surfaces for contact simulations, tie constraints, fasteners, and coupling, as
well as regions for distributed surface loads, acoustic radiation, acoustic impedance, and output of integrated
quantities on a surface. In ABAQUS/Standard it is also used to define surfaces for cavity radiation analysis
and assembly loads. In ABAQUS/Explicit this option can also be used to define boundary regions on adaptive
mesh domains.
Products: ABAQUS/Standard ABAQUS/Explicit

Required parameter:
NAME
Set this parameter equal to a label that will be used to refer to the surface.
Required parameter for cavity radiation simulations:
PROPERTY
This parameter applies only to ABAQUS/Standard analyses.
Set this parameter equal to the name of the *SURFACE PROPERTY definition associated with
this surface. See “Cavity radiation,” Section 32.1.1 of the ABAQUS Analysis User’s Manual.
Optional parameters:
COMBINE
Set COMBINE=UNION to create a surface based on the union of two or more surfaces of the same
type.
