Boundary Conditions

use if tangential phase speed in radiation conditions

use if enhanced viscosity/diffusion areas

Options for eastern edge open boundary conditions

Select only one option for free-surface, 2D momentum, 3D momentum, and tracers. The turbulent kinetic energy (TKE) conditions are only activated for the Generic length scale or Mellor-Yamada 2.5 vertical mixing closures. If open boundary radiation conditions, an additional option can be activated at each boundary edge to include a passive (active) nudging term with weak (strong) values for outflow (inflow).
