◆ reconstruct_fd_neighbor_work()

template<typename TagsList , typename PrimsTags , size_t Dim, typename F0 , typename F1 >
void NewtonianEuler::fd::reconstruct_fd_neighbor_work ( gsl::not_null< Variables< TagsList > * >  vars_on_face,

size_t  ghost_zone_size 
)

Reconstructs the mass density, velocity, and pressure, then computes the specific internal energy and conserved variables. All results are written into vars_on_face.

This is used on DG elements to reconstruct their subcell neighbors' solution on the shared faces.
