leapfrog.F @ 1549

Last change on this file since 1549 was 1549, checked in by emillour, 9 years ago

All GCMs:
Further adaptations to keep up with changes in LMDZ5 concerning
physics/dynamics separation (up to rev r2420 of LMDZ5)

all physics packages:
added module callphysiq_mod.F90 in dynphy_lonlat/phy* which contains the routine "call_physiq" which is called by calfis* and calls the physics. This way different "physiq" routine from different physics packages may be called: The calfis* routines now exposes all available fields that might be transmitted to physiq but which is actually send (ie: expected/needed by physiq) is decided in call_physiq.
turned "physiq.F[90]" into module "physiq_mod.F[90]" for better control of "physiq" arguments. for phyvenus/phytitan, extracted gr_fi_ecrit from physiq.F as gr_fi_ecrit.F90 (note that it can only work in serial).

misc:
updated wxios.F90 to keep up with LMDZ5 modifications.

dyn3d_common:
infotrac.F90 keep up with LMDZ5 modifications (cosmetics)

dyn3d:
gcm.F90: cosmetic cleanup.
leapfrog.F90: fix computation of date as function of itau.

dyn3dpar:
gcm.F: cosmetic cleanup.
leapfrog_p.F90: fix computation of date as function of itau.

NB: physics are given the date corresponding to the end of the
physics step.

dynphy_lonlat:
calfis.F : added computation of relative wind vorticity.
calfis_p.F: added computation of relative wind vorticity (input required by Earth physics)
