pure virtual

Compute the boundary flux given a state (a_phi will be different for different RTE approximations)

Parameters

Note: The return vector should have the same order as the boxes in a_dbl. E.g. ret[0] must be the load for a_dbl.boxArray()[0];

The default implementation returns the number of cells in the grid patch as a proxy for the load.
