26 !-------------------------------------------------------------------
27 ! this is a wrapper for the solver-specific init_domain routines.
28 ! Also dereferences the grid variables and passes them down as arguments.
29 ! This is crucial, since the lower level routines may do message passing
30 ! and this will get fouled up on machines that insist on passing down
31 ! copies of assumed-shape arrays (by passing down as arguments, the
32 ! data are treated as assumed-size -- ie. f77 -- arrays and the copying
33 ! business is avoided). Fie on the F90 designers. Fie and a pox.
