73!-- Here the user-defined grid initializing actions follow:
74
75!
76!-- Set the index array nzb_local for non-flat topography.
77!-- Here consistency checks concerning domain size and periodicity are necessary
78    SELECT CASE ( TRIM( topography ) )
79
80       CASE ( 'flat', 'single_building', 'single_street_canyon' )
81!
82!--       Not allowed here since these are the standard cases used in init_grid.
83
84       CASE ( 'user_defined_topography_1' )
85!
86!--       Here the user can define his own topography.
87!--       After definition, please remove the following three lines!
88          message_string = 'topography "' // topography // '" not available yet'

93!--       The DEFAULT case is reached if the parameter topography contains a
