|[[Check_Files_2d_DEM_M | _DEM_M<br>_DEM_M]]|| A DEM of the final material ID values, similar to the DEM_Z check grid described below. The .tcf command Grid Format can be used output this check file in ASCII format rather than the default FLT format.
|-
|[[Check_Files_2d_DEM_Z | _DEM_Z<br>_DEM_Z]]|| A DEM of the final ground/bathymetry elevations, including those from any 1D WLL mesh. The file is given a DEM_Z extension, and can be readily opened by most GIS and other GUIs. The default size of the grid cells is half the smallest 2D cell size. This can be changed using the <font color="blue"><tt>Grid Output Cell Size </tt></font> <font color="red"><tt>==</tt></font> command. To exclude writing this file, include “DEM_Z” in the Write Check Files EXCLUDE list. The <font color="blue"><tt>Grid Format </tt></font> <font color="red"><tt>==</tt></font> command can be used to control the format of the file. <br>
The DEM_M and DEM_Z check grids are written if the model start up is forced to only process the .tgc file. To do this, don’t specify or comment out, the BC Control File command.

|-
|[[Check_Files_2d_bg_uvpt_check | _bg_uvpt_check<br>_bg_uvpt_check]]|| Contains information on adjustments to the ZU/ZV cell sides as modified by <font color="blue"><tt>Read GIS BG Shape</tt></font> <font color="red"><tt> ==</tt></font> command.
|-
| [[Check_Files_2d_bcc_check | _bcc_check<br>_bcc_check_R<br>]]|| GIS files providing trace back information and uses cells, rather than point/line objects to show 2D BCs.
|-
| [[Check_Files_2d_dom | _dom_check<br>_dom_check_R]]|| Contains a rectangle for each 2D domain showing the location, orientation and size of the domain. Within this domain, cells can be turned on or off, outside this domain no 2D calculations can be performed.
|-
| [[Check_Files_2d_fc | _fc_check<br>_fc_check_R]]|| GIS layer of the final arrangement of flow constrictions (FC). The flow constrictions are written as individual square cells of the same shape as the grid cells, even if the FC was specified using points or lines/polylines.
|-
| [[Check_Files_2d_fcsh_uvpt | _fcsh_uvpt_check<br>_fcsh_uvpt_check_P]]|| Contains information on adjustments to the ZU/ZV cell sides as modified by <font color="blue"><tt>Read GIS FC Shape </tt></font> <font color="red"><tt>==</tt></font> commands.
|-
| [[Check_Files_2d_glo | _glo_check<br>_glo_check_P]]|| GIS layer of any gauge level output (GLO) locations.
|-
| [[Check_Files_2d_grd | _grd_check<br>_grd_check_R]]|| GIS layer of the final 2D grid. Represents the final grid including modifications from the .tgc file, boundary specifications and flow constrictions. Note that the Material and bed resistance (eg. Mannings_n) attributes do not include any modifications due to flow constrictions as these are applied directly to the cell mid-sides (rather than the cell centre). To view these use the [[Check_Files_2d_uvpt|_uvpt_check file]] file.<br>
Can also be written at different stages within a .tgc file (see <font color="blue"><tt>Write GIS Grid </tt></font> <font color="red"><tt>==</tt></font> command). The file contains all modifications to the 2D grid at the point in the .tgc file that it is written. <br>
Note that a number of additional attributes are appended to the_grd_check layer when some features of TUFLOW have been used.
| [[Check_Files_2d_input_layers | _input_layers]]|| GIS layer containing full filepaths to all input layers used to compile the model.
|-
| [[Check_Files_2d_lfcsh_uvpt | _lfcsh_uvpt_check<br>_lfcsh_uvpt_check_P]]|| Contains information on adjustments to the ZU/ZV cell sides as modified by <font color="blue"><tt>Read GIS Layered FC Shape</tt></font> <font color="red"><tt>==</tt></font> commands.
|-
| [[Check_Files_2d_LP | _lp_check<br>_lp_check_L]]|| GIS layer of any 2D longitudinal profile(s).
|-
| [[Check_Files_2d_PO | _po_check<br>_po_check_P<br>_po_check_L]]|| GIS layer of any 2D plot output location(s). The layer shows points and lines occurring from the cell centres, rather than their exact locations in the original file(s). For the shapefile the points and lines are output in separate files.
|-
| [[Check_Files_2d_sac | _sac_check<br>_sac_check_R]]|| GIS layer of the lowest cell selected for <font color="blue"><tt>Read GIS SA</tt></font> inputs, and cells selected if using <font color="blue"><tt>Read GIS SA PITS</tt></font>.
|-
| [[Check_Files_2d_sh_obj | _sh_obj_check<br>_sh_obj_check_R]]|| Contains objects such as buffer polygons used for wide lines, triangles generated for TINs within polygons, and regions and polylines for thick and thin lines to illustrate areas that have been modified by Create TIN Zpts (if the WRITE TIN option is specified), Read GIS Z Shape, Read GIS Variable Z Shape, Read GIS FC Shape and Read GIS Layered FC Shape commands.
|-
| [[Check_Files_2d_uvpt | _uvpt_check<br>_uvpt_check_P]]|| GIS layer containing the initial velocities, roughness value, FLC, WrF, FC lid depth and FC BD factor at the U and V points. For materials that vary Manning’s n with depth, the Manning_n attribute contains the Manning’s n value at the higher depth.
|-
| [[Check_Files_2d_vzsh | _vzsh_check<br>_vzsh_check_P<br>_vzsh_check_L]]|| Contains information on Zpts that have been modified by <font color="blue"><tt>Read GIS Variable Z Shape </tt></font> <font color="red"><tt>==</tt></font> commands.
|-
| [[Check_Files_2d_zln_zpt | _zln_zpt_check<br>_zln_zpt_check_P]]|| GIS layer containing Zpts that have been modified by <font color="blue"><tt>Read GIS Z Line </tt></font> <font color="red"><tt>==</tt></font> commands, the type of Z Line and the Z Line filename. This feature is very useful for checking which Zpts that the Z Lines have modified. '''Note: It does not include any GULLY lines.'''<br>
When written in .mif/.mid format, the points are given different symbology according to whether they have been raised or lowered (up or down triangles) or remain unchanged (a cross).
|-
| [[Check_Files_2d_zpt | _zpt_check<br>_zpt_check_P]]|| GIS layer of the final 2D Zpts. Represents the final Zpts including all modifications from the .tgc file, and any flow constrictions in the .tcf file.<br>
Can also be written at different stages within a .tgc file (see the <font color="blue"><tt>Write GIS Zpts</tt></font> command). The file contains all modifications to the 2D Zpts at the point in the .tgc file that it is written. This allows checking of the elevations at different stages of building the topography.
|-
| [[Check_Files_2d_zsh_zpt | _zsh_zpt_check<br>_zsh_zpt_check_P]]|| Contains Zpts that have been modified by <font color="blue"><tt>Read GIS Z Shape </tt></font> <font color="red"><tt>==</tt></font> commands. When written in .mif/.mid format, the points are given different symbology according to whether they have been raised or lowered (up or down triangles) or remain unchanged (a cross).
