!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. !----------------------------------------------------------------------- MODULE module_initialize_ideal USE module_domain USE module_io_domain USE module_state_description USE module_model_constants USE module_bc USE module_timing USE module_configure USE module_init_utilities #ifdef DM_PARALLEL USE module_dm #endif 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).
