Message:

Redefine initial nzb_local as the actual total size of topography (later the
extent of topography in nzb_local is reduced by 1dx at the E topography walls
and by 1dy at the N topography walls to form the basis for nzb_s_inner);
for consistency redefine 'single_building' case.

These data must exactly match the horizontal grid. Due to the staggered grid the topography will be displaced by -0.5 dx in x-direction and -0.5 dy in y-direction.
