TUFLOW HR Output: Difference between revisions

When modelling breaklines in TUFLOW, thin breaklines modify the cell face elevations but do not modify the cell storages. When outputting the high-resolution outputs, the user can setchoose whether the cell face elevations are included using the following .tcf command.

* “ON” (default): use face elevations in [[Check_Files_2d_DEM_Z_HR | _DEM_Z_HR]] check file. This option clearlyaccurately shows the cell faces where water can be hydraulically blocked. However, when cell faces are angled with the thin breakline, this can create 'pockets' of lower elevations in the check file that does not exist in reality.

* “OFF”: Face elevations are not used in [[Check_Files_2d_DEM_Z_HR | _DEM_Z_HR]] check file. This is an useful option for report writing, as 'clean' high resolution DEM images can be generated reflecting all geometry updates except for the Thin Breakline updates at cell faces.
