69!-- Here the user-defined grid initializing actions follow:
70
71!
72!-- Set the index array nzb_local for non-flat topography.
73!-- Here consistency checks concerning domain size and periodicity are necessary
74    SELECT CASE ( TRIM( topography ) )

76       CASE ( 'flat', 'single_building', 'single_street_canyon' )

78!--       Not allowed here since these are the standard cases used in init_grid.
79
80       CASE ( 'user_defined_topography_1' )
81!
82!--       Here the user can define his own topography.
83!--       After definition, please remove the following three lines!
84          message_string = 'topography "' // topography // '" not available yet'
