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

20 USE module_state_description
21 USE module_model_constants
25 USE module_init_utilities
34 !-------------------------------------------------------------------
35 ! this is a wrapper for the solver-specific init_domain routines.
36 ! Also dereferences the grid variables and passes them down as arguments.
37 ! This is crucial, since the lower level routines may do message passing
38 ! and this will get fouled up on machines that insist on passing down
39 ! copies of assumed-shape arrays (by passing down as arguments, the
40 ! data are treated as assumed-size -- ie. f77 -- arrays and the copying
41 ! business is avoided). Fie on the F90 designers. Fie and a pox.
