[668]	15	!
[674]	16	! 673 2011-01-18 16:19:48Z suehring
	17	! weight_substep (moved from advec_ws) and weight_pres added.
	18	! Allocate p_sub when using Multigrid or SOR solver.
	19	! Call of ws_init moved behind the if requests.
	20	!
[668]	21	! 667 2010-12-23 12:06:00Z suehring/gryschka
[667]	22	! nxl-1, nxr+1, nys-1, nyn+1 replaced by nxlg, nxrg, nysg, nyng in loops and
	23	! allocation of arrays. Calls of exchange_horiz are modified.
	24	! Call ws_init to initialize arrays needed for statistical evaluation and
	25	! optimization when ws-scheme is used.
	26	! Initial volume flow is now calculated by using the variable hom_sum.
	27	! Therefore the correction of initial volume flow for non-flat topography
	28	! removed (removed u_nzb_p1_for_vfc and v_nzb_p1_for_vfc)
	29	! Changed surface boundary conditions for u and v in case of ibc_uv_b == 0 from
	30	! mirror bc to dirichlet boundary conditions (u=v=0), so that k=nzb is
	31	! representative for the height z0
	32	! Bugfix: type conversion of '1' to 64bit for the MAX function (ngp_3d_inner)
	33	!

[333]	51	! bugfix: avoid that ngp_2dh_s_inner becomes zero
[328]	52	! initializing_actions='read_data_for_recycling' renamed to 'cyclic_fill', now
	53	! independent of turbulent_inflow
[254]	54	! Output of messages replaced by message handling routine.
[240]	55	! Set the starting level and the vertical smoothing factor used for
	56	! the external pressure gradient
