!IDEAL:MODEL_LAYER:INITIALIZATION
!
! This MODULE holds the routines which are used to perform various initializations
! for the individual domains.
! This MODULE CONTAINS the following routines:
! initialize_field_test - 1. Set different fields to different constant
! values. This is only a test. If the correct
! domain is not found (based upon the "id")
! then a fatal error is issued.

CONTAINS
!-------------------------------------------------------------------
! this is a wrapper for the solver-specific init_domain routines.
! Also dereferences the grid variables and passes them down as arguments.
! This is crucial, since the lower level routines may do message passing
! and this will get fouled up on machines that insist on passing down
! copies of assumed-shape arrays (by passing down as arguments, the
! data are treated as assumed-size -- ie. f77 -- arrays and the copying
! business is avoided). Fie on the F90 designers. Fie and a pox.
! NOTE: Modified to remove all but arrays of rank 4 or more from the
! argument list. Arrays with rank>3 are still problematic due to the
! above-noted fie- and pox-ities. TBH 20061129.
