Whereas the total land-ice freshwater flux (landIceFreshwaterFluxTotal is computed correctly in simulations with prognostic ice-shelf melt fluxes (PISMF) as the sum of the flux at the ice-ocean interface, landIceFreshwaterFlux, and the frazil flux, frazilIceFreshwaterFlux, this is not the case when ice-shelf melt fluxes come from a data file (DISMF).

See, for example, these MPAS-Analysis plots showing seemingly no melt fluxes:
