wake.F90 @ 5423

Last change on this file since 5423 was 2922, checked in by fhourdin, 8 years ago
Nouvelle option iflag_wk_check_trgl pour tester la bonne sante des poches. L'ancien flag logique flag_wk_check_trgl est toujours utilisable. Il vaut y/n si iflag_wk_check_trgl=1/0. L'option 1 avait tendance à faire disparaitre les poches dans des cas 1D. L'option 2 est donc précaunisée pour les réglages à venir. Fredho pour Jean-Yves
