compas_cem.loads ¤

Point loads applied to the nodes of a topology diagram.

Classes¤

NodeLoad ¤

NodeLoad(node, vector=[0.0, 0.0, -1.0], **kwargs)

A point load applied to one node of a diagram.

Parameters:

  • node –

    The key of the node to load.

  • vector –

    The xyz components of the load. Defaults to one unit downwards.

Methods:¤

from_point_and_vector classmethod ¤
from_point_and_vector(point, vector)

Create a load from a point and a vector.

Parameters:

  • point –

    The coordinates of the position where the load is applied.

  • vector –

    The xyz components of the load.

Returns:

  • load –

    A load with no node key, positioned at the given point.

Notes

The load binds to a diagram node whose coordinates match the point. If no node sits there, the load is not assigned.
