weights_from_xyz

compas_tno.algorithms.weights_from_xyz(xyz, F, V0, V1, V2, thk=0.5, density=20.0)[source]

Compute the tributary weights based on the assembled sparse matrices linking the topology

Parameters

  • xyz (array [n x 3]) – The XYZ coordinates of the thrust network

  • F (array [f x n]) – Linear transformation from X [n x 3] to c [f x 3] with the position of the centroids

  • V0 (array [g x n]) – Mark the influence of the original point in the calculation

  • V1 (array [g x n]) – Mark the influence of the neighbor points the calculation

  • V2 (array [g x f]) – Mark the influence of the centroid points the calculation

  • thk (float, optional) – The thickness of the structure to compute the tributary volumes, by default 0.5

  • density (float, optional) – The density of the structure to compute the applied vertical loads, by default 20.0

Returns

pz (array [n x 1]) – The vertical loads applied ar each node
