            ],
        ]
    ],
]: ...

No connectors are required for a constant policy.

Parameters

l0 Tuple[List[int], int] — Number of elements in layer a.
l1 Tuple[List[int], int] — Number of elements in layer b.
cs salvus.geometry.coordinates.coordinates.CoordinateSystem — The coordinate system.
layer_bounds Dict[str, Tuple[float, float]] — The bounds of the associated layer.

Returns Tuple[List[Tuple[int, Union[salvus.mesh.layered_meshing.meshing_protocol.coarsening_policy._InterlayerConnectorProtocol2D, salvus.mesh.layered_meshing.meshing_protocol.coarsening_policy._InterlayerConnectorProtocol3D]]], List[Tuple[int, Union[salvus.mesh.layered_meshing.meshing_protocol.coarsening_policy._InterlayerConnectorProtocol2D, salvus.mesh.layered_meshing.meshing_protocol.coarsening_policy._InterlayerConnectorProtocol3D]]]] — A tuple of empty lists (no connectors).

`interlayer_constraint()`

def interlayer_constraint(
    self,
    a: List[ortools.sat.python.cp_model.IntVar],
    b: List[ortools.sat.python.cp_model.IntVar],
) -> List[List[ortools.sat.python.cp_model.BoundedLinearExpression]]: ...

Generate the interlayer constraints.

Parameters

a List[ortools.sat.python.cp_model.IntVar] — Number of horizontal elements in layer a.
b List[ortools.sat.python.cp_model.IntVar] — Number of horizontal elements in layer b.

Returns List[List[ortools.sat.python.cp_model.BoundedLinearExpression]] — An equality constant between a and b.
