Surfaces used in general contact interactions can span many disconnected regions of the model. To refine the contact domain, you can include or exclude specific surface pairs. Typically, general contact interactions are defined for an all-inclusive surface that contains all exterior faces feature edges and-in Abaqus/Explicit-analytical rigid surfaces, edges based on beams and trusses, and Eulerian material boundaries.
General contact is also used to define contact between Lagrangian bodies and Eulerian materials in a coupled Eulerian-Lagrangian analysis (see “Defining contact in Eulerian-Lagrangian models, ” Section 28.3). General contact interactions allow you to define contact between many or all regions of the model with a single interaction.
