Card  Supported Element Configurations  Description 

*COUPLING  Rigid/RBE3  Define a surfacebased coupling constraint where
the *SURFACE card points to elements. Note: The *COUPLING is also
supported as rigid elements (COUP_KIN) and RBE3 (COUP_DIS)
when *SURFACE points to nodes.

*ELEMENT 

Defines elements by giving their nodes. 
*ELGEN  Generates elements incrementally. These cards are resolved to individual entities on import and are written back on export the same way. Note: Standard 2D
only.


*MPC  Rigid  Defines multipoint constraints. 
*RELEASE 

Releases rotational degrees of freedom at one or
both ends of a beam element. For 2D problems, only dof6 (M1) is active. Add a *RELEASE card to this element by
clicking pins a = and pins b = and type in the HyperMesh dof code for the Abaqus release combination code you
want.
