wake.F90 @ 4867

Last change on this file since 4867 was 2922, checked in by fhourdin, 7 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
