Elements
Elements are FE idealizations for a portion of a physical part.
Every element must be organized into one component, and therefore are mutually exclusive to a component.
Element Configurations
Each element has an associated element configuration. An element configuration tells HyperWorks how to draw, store, and work with the element.
Bar Elements
1D elements created in a space between two or three nodes of a model where beam properties are desired.
The nodes are related to each other based on the properties of the bar or beam element connecting them. Properties associated with bar elements include vector orientation, offset vectors that end at A and B, or at A, B, and C, and pin flags to tell it what degree of freedom should carry through the beam.
Bar elements are displayed as a line between two nodes with BAR2 or BAR3 written at the centroid of the element.
 Bar2
 Configuration 60  1D (1st order) elements with 2 nodes used to model axial, bending, and torsion behavior. Bar2 elements have a property reference, an orientation vector, offset vectors and ends A and B, and pin flags at ends A and B.
 Bar3
 Configuration 63  1D (2nd order) elements with 3 nodes used to model axial, bending, and torsion behavior. Bar3 elements have a property reference, an orientation vector, offset vectors and ends A and B, and pin flags at ends A and B.
Gap Elements
Configuration 70  1D elements created in a space between two nodes, or between a node and an element, of a model where contact may occur.
Create a gap element when you want to impose a nonlinear constraint on a model; this constraint will limit the amount of movement possible during analysis.
Gap elements have a property reference and an orientation vector.
Gap elements are displayed as a line between two nodes with GAP written at the centroid of the element.
Gap elements can translate to CGAP or CGAPG elements in OptiStruct, CGAP element in Nastran or *GAP option in Abaqus.
Hex Elements
3D hexahedra elements.
 Hex8
 Configuration 208  3D (1st order) hexahedra elements with 8 nodes.
 Hex20
 Configuration 220  3D (2nd order) hexahedra elements with 20 nodes.
Joint Elements
Configuration 22  1D elements with 2, 4, or 6 nodes which have a property and orientation systems or nodes.
Joint element is a definition of a connection between two rigid bodies. Joint elements store a property and orientation information.
Joint elements are displayed with lines between the appropriate nodes and the letter J between nodes 1 and 3 of the element.

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 HyperWorks dof code for the Abaqus release combination code you
