property Simulation3DCellCentered.surface_faces

Array defining which boundary faces to interpret as surfaces of Neumann boundary

DC problems will always enforce a Neumann boundary on surface interfaces. The default (available on semi-structured grids) assumes the top interface is the surface.

Returns:

None or (n_bf, ) numpy.ndarray of bool
