Element-based surface definition

An element-based surface:

  • can be defined on solid, structural, rigid, surface, gasket, or acoustic elements;

  • can be deformable or rigid;

  • can be defined on any combination of elements in many cases;

  • can be defined on the exterior of any body; and

  • can be defined on the interior of any body that is modeled with continuum, shell, membrane, surface, beam, pipe, truss, or rigid elements (e.g., to define a cross-section through a body) either by simply cutting the body with a plane or by identifying the elements and the corresponding interior facets.

For details about defining node-based surfaces, see Node-based surface definition. For details about defining analytical rigid surfaces, see Analytical rigid surface definition. For details about defining surfaces using Boolean combinations of existing surfaces, see Operating on surfaces.
