- ! 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.
