Node

class compas_fea2.model.Node

Bases: FEAData

Class representing a Node object.

Parameters:

xyzlist[float, float, float] | compas.geometry.Point

The location of the node in the global coordinate system.

massfloat or tuple, optional

Lumped nodal mass, by default None. If float, the same value is used in all 3 directions. if you want to specify a different mass for each direction, provide a tuple as (mass_x, mass_y, mass_z) in global coordinates.

temperaturefloat, optional

The temperature at the Node.

namestr, optional

Uniqe identifier. If not provided it is automatically generated. Set a name if you want a more human-readable input file.

Notes

Nodes are registered to a compas_fea2.model.Part object and can belong to only one Part. Every time a node is added to a Part, it gets registered to that Part.

Examples

>>> node = Node(xyz=(1.0, 2.0, 3.0))

Attributes:

namestr

Uniqe identifier. If not provided it is automatically generated. Set a name if you want a more human-readable input file.

masstuple

Lumped nodal mass in the 3 global directions (mass_x, mass_y, mass_z).

keystr, read-only

The identifier of the node.

xyzlist[float]

The location of the node in the global coordinate system.

xfloat

The X coordinate.

yfloat

The Y coordinate.

zfloat

The Z coordinate.

gkeystr, read-only

The geometric key of the Node.

dofdict

Dictionary with the active degrees of freedom.

on_boundarybool | None, read-only

True if the node is on the boundary mesh of the part, False otherwise, by default None.

is_referencebool, read-only

True if the node is a reference point of compas_fea2.model.RigidPart, False otherwise.

partcompas_fea2.model._Part, read-only

The Part where the element is assigned.

modelcompas_fea2.model.Model, read-only

The Model where the element is assigned.

pointcompas.geometry.Point

The Point equivalent of the Node.

temperaturefloat

The temperature at the Node.
