compute_interface_fluxes() void pism::GeometryEvolution::compute_interface_fluxes ( const array::CellType1 &  cell_type, const array::Scalar &  ice_thickness, const array::Vector &  velocity, const array::Staggered &  diffusive_flux, array::Staggered &  output  ) protectedvirtual Combine advective velocity and the diffusive flux on the staggered grid with the ice thickness to compute the total flux through cell interfaces. Uses first-order upwinding to compute the advective flux. Limits the diffusive flux to prevent SIA-driven flow in the ocean and ice-free areas. Reimplemented in pism::RegionalGeometryEvolution.
