Advection scheme for momentum:
- : No advection of momentum, i.e.
- : First-order upwind for momentum.
- : Second-order central for momentum. Note that diffusion must be present for stability. While
it is difficult to perform an exact stability analysis for the unstructured-grid equations, the 1-d
stability limitation requires that
grid Peclet number according to
which translates into the requirement that the horizontal diffusion be restricted to
Equivalently, the vertical diffusion is restricted by
