/*! @brief Sortie_libre_pression_imposee This class derives from Neumann_sortie_libre.
 *
 *     It represents an open boundary with an imposed pressure condition.
 *     The Champ_bord object le_champ_bord contains the pressure and the function flux_impose() returns the values of this pressure.
 *     champ_ext contains a value of the fluid velocity outside, accessible via the val_ext() method.
