SimPEG.electromagnetics.utils.segmented_line_current_source_term(mesh, locs)[source]#

Calculate a source term for a line current source on a mesh

Given a discretize mesh, compute the source vector for a unit current flowing along the segmented line path with vertices defined by locs.

meshdiscretize.TreeMesh or discretize.TensorMesh

The Mesh (3D) for the system.

locs(n_points, 3) numpy.ndarray

The array of locations of consecutive points along the polygonal path.

(mesh.n_edges) numpy.ndarray

Contains the source term for all x, y, and z edges of the mesh.


You can create a closed loop by setting the first and end point to be the same.
