property Simulation2DCellCentered.surface_faces#

Array defining which 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 numpy.ndarray of bool
