Common dynamical core:
Updates in the dynamics to keeup up with updates in LMDZ5
(up to LMDZ5 trunk rev 2200):
- compilation:
- create_make_gcm : added processing of .f & .f90 files (not just .F and .F90)
- makelmdz: add "mix" option for -io (ouptut with both IOIPSL and XIOS)
- makelmdz_fcm: add "mix" option for -io
- filtrez:
- acc.F and eigen.F : add "implicit none" and variable declarations
- bibio:
- handle_err_m.F90: replace "stop" with call to abort_gcm()
- i1mach.F, j4save.F: add "implicit none" and variable declarations
- xercnt.F, xermsg.F, xerprn.F, xersve.F, xgetua.F: add "implicit none"
and variable declarations
- dyn3d_common:
- disvert.F90 : added comments on meaning of "pa" variable
- grid_atob.F : better control on level of default ouputs
- infotrac.F90: update Earth-specific stuff (nqo water tracers)
- interpre.F: correction on the size of input array w
- juldate.F, massbar.F, ppm3d.F, ran1.F: add "implicit none"
and variable declarations
- sortvarc.F: code cleanup
- iniacademic.F90: cleanup and extra sanity check.
- dyn3d:
- abort_gcm.F: additions for XIOS
- conf_gcm.F90: transformed to free form from conf_gcm.F
- gcm.F: added test to check that iphysiq is a multiple of iperiod
- getparam.F90, guidz_mod.F: update from LMDZ5
- integrd.F: replace stop with call_abort()
- dyn3dpar:
- abort_gcm.F: minor cleanup
- gcm.F: added test to check that iphysiq is a multiple of iperiod
- getparam.F90, guide_p_mod.F90: update from LMDZ5
- integrd_p.F: abort with call_abort when there is negative surface pressure
- leapfrog_p.F: add INCA specific stuff to keep up with current LMDZ5
- conf_gcm.F90: transformed to free form from conf_gcm.F
