r559 r667 4 4 ! Current revisions: 5 5 !  6 ! 6 ! Definition of new array bounds nxlg, nxrg, nysg, nyng on each PE. 7 ! Furthermore the allocation of arrays and steering of loops is done with these 8 ! parameters. Call of exchange_horiz are modified. 9 ! In case of dirichlet bounday condition at the bottom zu(0)=0.0 10 ! dzu_mg has to be set explicitly for a equally spaced grid near bottom. 11 ! ddzu_pres added to use a equally spaced grid near bottom. 7 12 ! 8 13 !
