!!**** *CONTRAV * - computes the contravariant components from the
!! cartesian components
!!
!! PURPOSE
!! -------
! This routine computes the contravariant components of vector
! defined by its cartesian components (U,V,W) , using the following
! formulae:
! UC = U / DXX
! VC = V / DYY
! ( ----------x ----------y )
! ( ---z ---z )
! 1 ( U V )
! WC = --- ( W - DZX * --- - DZY * --- )
! DZZ ( DXX DYY )
!
!
! In the no-topography case, WC = W / DZZ
!
!
!!** METHOD
!! ------
!! We employ the Shuman operators to compute the averages. The metric
!! coefficients PDXX, PDYY, PDZX, PDZY, PDZZ are dummy arguments
!!
!!

!!**** *CONTRAV * - computes the contravariant components from the
!! cartesian components
!!
!! PURPOSE
!! -------
! This routine computes the contravariant components of vector
! defined by its cartesian components (U,V,W) , using the following
! formulae:
! UC = U / DXX
! VC = V / DYY
! ( ----------x ----------y )
! ( ---z ---z )
! 1 ( U V )
! WC = --- ( W - DZX * --- - DZY * --- )
! DZZ ( DXX DYY )
!
!
! In the no-topography case, WC = W / DZZ
!
!
!!** METHOD
!! ------
!! We employ the Shuman operators to compute the averages. The metric
!! coefficients PDXX, PDYY, PDZX, PDZY, PDZZ are dummy arguments
!!
!!
!! EXTERNAL
!! --------
!! MXF, MYF, MZM : Shuman functions (mean operators)
!!
!! Module MODI_SHUMAN : Interface for Shuman functions
