in $LMDGCM/libf/dyn3d

gcm ->  Initialisation (iniconst, inigeom, inidissip, iniwrite ...)
        leapfrog : time integration

leapfrog ->  caldyn  : computes dynamical tendencies
             integrd : add dynamical tendencies to dynamical variables
             calfis  : call ../phylmd/physiq.F which computes physical tendencies
             addfi   : add physical tendencies
             dissip  : lateral diffusion

Interface with physics

calfis -> transforms dynamical variables into physical variables
          ( ucov -> u , teta -> T, etc ... + change of grid)
          call physiq (../phylmd/physiq.F)
          transforms physical tendencies to come back to conventions
          of the dynamics.


in $LMDGCM/libf/phylmd

physiq -> monitor of the physical package.
            clmain    : boundary layer
            concvl    : convection
            ajsec     : dry convective adjustment
