| TUFLOW 2D domains are cartesian (rectilinear) grids. 2D domains are created using a [[SMS:Cartesian Grid Frame|Cartesian Grid Frame]] inside a [[SMS:TUFLOW Coverages#Grid Extents Coverage|TUFLOW Grid Extents Coverage]].

| Grids store elevation values at each corner, midside, and center. There are several [[SMS:TUFLOW Grid Options | Grid Options]] that apply to a grid that can be specified by right-clicking on the grid and choosing ''Properties''.

| A 2D domain is represented as a [[SMS:TUFLOW 2D Geometry Components|2D Geometry Component]] in the TUFLOW interface. A 2D Geometry component includes the grid and associated coverages.

| | |
| Grid elevations can be modified using the select grid location tool by selecting and changing the z values at specific directions. A [[SMS:TUFLOW Coverages#2D Geometry Modification Coverage|2D TUFLOW Geometry Modification Coverage]] can also be used to force elevations using arcs or polygons.
| |
| | |
| Multiple grids can be used inside the same simulation. The grid used in each area of the domain is specified using a [[SMS:TUFLOW Coverages#2D/2D Links Coverage|TUFLOW 2D/2D Link Coverage]].
