C !ROUTINE: WRITE_GRID
C !INTERFACE:
SUBROUTINE WRITE_GRID(
I myThid )
C !DESCRIPTION:
C Writes the model geometry and grid arrays to file(s) using which
C ever I/O package is available/active. This includes horizontal
C and vertical grid and finite volume modulating factors (hFacs).
C Essentailly, it dumps the contents of GRID.h to disk.
C !CALLING SEQUENCE:

C !INPUT/OUTPUT PARAMETERS:
C myThid - Number of this instances
INTEGER myThid
C !LOCAL VARIABLES:
character*(4) bfname
C tmpfld - Temporary array used to compute & write Total Depth
C has to be in common for multi threading
C ?aja: not sure why the COMMON block is necessary - should ask JMC?

C Calculate the fluid thickness in R coordinates as seen by the
C model. This may differ from what the user specified due to
C partial cells, etc.
