_Element

class compas_fea2.model._Element

Bases: FEAData, Frameable

Initialises a base Element object.

Parameters:

nodeslist[compas_fea2.model.Node]

Ordered list of node identifiers to which the element connects.

sectioncompas_fea2.model._Section

Section Object assigned to the element.

implementationstr, optional

The name of the backend model implementation of the element.

rigidbool, optional

Define the element as rigid (no deformations allowed) or not. Defaults to False.

heatbool, optional

Define the element as a heat transfer element. Defaults to False.

framecompas.geometry.Frame, optional

Optional local reference frame. If not provided, the GLOBAL frame is assumed (via Frameable).

Attributes:

keyint, read-only

Identifier of the element in the parent part.

nodeslist[compas_fea2.model.Node]

Return the list of nodes to which the element is connected.

nodes_keystr, read-only

Identifier based on the connected nodes.

sectioncompas_fea2.model._Section

Return the section object assigned to the element.

implementationstr

Return the implementation name of the element.

partcompas_fea2.model.Part | None

Return the part to which the element is registered.

on_boundarybool | None

Return whether the element has a face on the boundary mesh.

modelcompas_fea2.model.Model, read-only

Return the model to which the element belongs.

areafloat, read-only

Return the element area in the active unit system.

volumefloat, read-only

Return the element volume in the active unit system.

rigidbool, read-only

Return whether the element is rigid.

heatbool, read-only

Return whether the element is a heat transfer element.

Warning

When an Element is added to a Part, the nodes of the elements are also added and registered to the same part. This might change the original registration of the nodes!

Notes

Elements and their nodes are registered to the same compas_fea2.model._Part and can belong to only one Part.
