    66Starting from this revision, overhanging structures (e.g. bridges, ceilings or tunnels) are allowed, i.e. topography does not necessarily be surface-mounted.

    8 The topography implementation described in Sect. [wiki:/doc/tec/bc#Topography boundary conditions] allows the use of 2-D topography height data (if no overhanging structures should be considered), or 3-D topography information. The topography input data has to be provided within a rastered [../../app/iofiles#TOPOGRAPHY ASCII] or [../../app/iofiles#TOPOGRAPHY2 NetCDF] file. Rastered 3-D topography consists of values either 1 (within topography) or 0 (outside topography), and has to be provided up to the level of the highest present topography structures.

    99After reading and mapping of topography data to the 3-D grid in PALM, flag arrays are set in order to mask grid boxes within the integration loops accordingly.
