!!****  *WRITE_LFIFM_n* - routine to write LB fields in the LFIFM file
!!
!!    PURPOSE
!!    -------
!        The purpose of this routine is to write LB fields in the
!     YFMFILE//'.lfi' with the FM routines.  
!
!!**  METHOD
!!    ------
!!       The LB fields (distributed on the processors) are gathered. Then
!!       they are writen on the file.
!!
!!    EXTERNAL
!!    --------
!!      FMWRIT : FM-routine to write a record
!!      GET_DISTRIBX_LB :  to get the indices of the LB arrays
!!      GET_DISTRIBY_LB    for each sub-domain
!!
!!
!!    IMPLICIT ARGUMENTS
