discretize.CurvilinearMesh.boundary_face_outward_normals

property CurvilinearMesh.boundary_face_outward_normals

Outward normals of boundary faces

For all boundary faces in the mesh, this property returns the unit vectors denoting the outward normals to the boundary. The returned quantity is a numpy array of shape (n_boundary_faces, dim).

Returns
(n_boundary_faces, dim) numpy.ndarray of float

Outward normals of boundary faces
