discretize.TreeMesh.average_node_to_face_x#
- TreeMesh.average_node_to_face_x#
Averaging operator from nodes to x faces (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 faces.
- Returns:

n_faces_x,n_nodes)scipy.sparse.csr_matrix The scalar averaging operator from nodes to faces
