Upwind divergence scheme

Properties​

  • First order
  • Bounded
  • Face value set according to the upstream value
  • Equivalent to assuming that the cell values are isotropic with a value that represents the average value

ϕf=ϕc\phi_f = \phi_c

{
    default         none;
    div(phi,U)      Gauss upwind;
}
