discretize.TensorMesh.project_face_vector

TensorMesh.project_face_vector(face_vectors)

Project vectors onto the faces of the mesh.

Consider a numpy array face_vectors whose rows provide a vector for each face in the mesh. For each face, project_face_vector computes the dot product between a vector and the corresponding face’s unit normal vector. That is, project_face_vector projects the vectors in face_vectors to the faces of the mesh.

Parameters:

face_vectors(n_faces, dim) numpy.ndarray

Numpy array containing the vectors that will be projected to the mesh faces

Returns:

(n_faces) numpy.ndarray of float

Dot product between each vector and the unit normal vector of the corresponding face
