About surfaces

In Abaqus surfaces:

  • can be used to define contact and interactions, including acoustic-structural interactions;

  • can define regions used to prescribe distributed surface loads;

  • can be used to tie dissimilar meshes together;

  • can define cavities used for a cavity radiation analysis in Abaqus/Standard;

  • can define pre-tensioned sections used in prescribing assembly loads in Abaqus/Standard;

  • can define sections used for tracking the average motion of a surface in Abaqus/Explicit;

  • can define sections for output quantities such as the total force transmitted through a surface;

  • are geometric entities that have an area associated with them but have zero volume;

  • have an identifiable orientation defined by their normals;

  • are defined by specifying nodes or node sets, an analytic curve or surface, an Eulerian material instance, or element faces, edges, or ends; and

  • can be deformable, rigid, or partially deformable and partially rigid.

This section describes the general rules that apply when creating surfaces in Abaqus.
