DiscontinuousFluxFunction

using ablate::finiteVolume::CellInterpolant::DiscontinuousFluxFunction = PetscErrorCode (*)(PetscInt dim, const PetscFVFaceGeom* fg, const PetscInt uOff[], const PetscScalar fieldL[], const PetscScalar fieldR[], const PetscInt aOff[], const PetscScalar auxL[], const PetscScalar auxR[], PetscScalar flux[], void* ctx)

Function assumes that the left/right solution and aux variables are discontinuous across the interface

PointFunction
