discretize.TreeMesh.average_node_to_edge_y

TreeMesh.average_node_to_edge_y

Averaging operator from nodes to y edges (scalar quantities).

This property constructs a 2nd order averaging operator that maps scalar quantities from nodes to edges. This averaging operator is used when a discrete scalar quantity defined on mesh nodes must be projected to edges.

Returns
(n_edges_y, n_nodes) scipy.sparse.csr_matrix
