Detailed Description

Neumann_sortie_libre This class represents an open boundary without imposed velocity.

For Navier-Stokes equations, pressure must be imposed on such a boundary. To handle the hydraulics, the class Sortie_libre_pression_imposee is derived from Neumann_sortie_libre. Boundary conditions of type Neumann_sortie_libre or derived types result in zero diffusive fluxes. However, the treatment of convective fluxes requires knowing the convected field outside the boundary in case of fluid re-entry. This is why the class carries an OWN_PTR(Champ_front_base) (member le_champ_ext).

In the computation operators, boundary conditions of type Neumann_sortie_libre and derived types will be treated identically.
