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.


Figure 1.
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.

Only certain types of elements can be used to create joint elements. The type of the element controls the number of nodes used in the element and the permissible orientations of the element.

RBE3 Elements

Configuration 56 - Rigid elements with one dependent node and variable independent nodes typically used to define the motion at the dependent node as a weighted average of the motions at the independent nodes.

Both the dependent node and independent nodes contain a coefficient (weighting factor) and user-defined degrees of freedom. The dependent degrees of freedom and weighting factors can be specified or automatically calculated based on the geometry.

RBE3 elements are displayed as lines between the dependent node and the independent node(s) with RBE3 displayed at the dependent node of the element.

RBE3’s are typically used to distribute loads applied on the dependent node amongst the selected independent nodes.
Note: The dependent node cannot be directly constrained, as this would lead to a double-dependency for that node.

Rigid Elements

Configuration 5 - Rigid 1D elements with 2 nodes used to model rigid connections.

Rigid elements are displayed as a line between two nodes with the letter R written at the centroid of the element.

Rigids can translate to RBE2 in Nastran or *MPC in Abaqus.

Rigidlink Elements

Configuration 55 - Rigid elements with one independent node and variable dependent nodes typically used to model rigid bodies.

Rigidlink elements have user-defined degrees of freedom which apply to all dependent nodes.

Rigidlink elements can be created with dependent nodes attached to an element as a SET. If a rigid link with a dependent node set is deleted, the associated node set is also deleted. If the dependent node set is deleted, the connected rigid link element is also deleted. Dependent node sets are automatically created when rigid link elements are created. A node set can be connected as a set of dependent nodes to a rigid link element independent node.
Note: Two-node rigids with a dependent node set attached are always created as rigid link elements

Rigidlink elements are displayed as lines between the independent node and the dependent node(s) with RL displayed at the independent node of the element.

Rod Elements

Configuration 61 - 1D elements with 2 nodes used to model axial behavior only.

The two nodes are related to each other based on the properties of the rod element connecting them. Rod elements have property pointers.
