# fd_numpy

compas.numerical.fd_numpy(vertices, edges, fixed, q, loads, **kwargs)[source]

Implementation of the force density method to compute equilibrium of axial force networks.

Parameters
• vertices (list) – XYZ coordinates of the vertices of the network

• edges (list) – Edges between vertices represented by

• fixed (list) – Indices of fixed vertices.

• q (list) – Force density of edges.

• loads (list) – XYZ components of the loads on the vertices.

Returns

• xyz (array) – XYZ coordinates of the equilibrium geometry.

• q (array) – Force densities in the edges.

• f (array) – Forces in the edges.

• l (array) – Lengths of the edges

• r (array) – Residual forces.
