guide_p_mod.F90 @ 1625

Last change on this file since 1625 was 1625, checked in by lguez, 12 years ago
Created logical variable "pressure_exner". "pressure_exner" replaces "disvert_type" to choose between calls to "exner_hyb" and "exner_milieu". If "pressure_exner" is true, pressure inside layers is computed from Exner function ("exner_hyb"), else it is the mean of pressure values at interfaces ("exner_milieu"). "disvert_type" now only chooses between "disvert" and "disvert_noterre". Default value for "pressure_exner" is true if "disvert_type" equals 1.
