discretize.base.BaseMesh.boundary_face_outward_normals#
- property BaseMesh.boundary_face_outward_normals#
Outward normal vectors of boundary faces.
This property returns the outward normal vectors of faces the boundary of the mesh as a numpy array. The shape of the numpy array is the number of boundary faces by the dimension of the mesh.
