!-------------------------------------------------------------------
! 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.
