==Model Domain==
The model domain can be manually set by viewing the terrain and manning’s data in your preferred GIS program, or set using the Read Grid Location command.<br><br><font color='green'><tt>!

==TUFLOW Code Layer==
The user can manually set the TUFLOW code layer by viewing the terrain data through their preferred GIS program or, it should be noted that MIKE uses a similar process of defining active cells, however does it through a ‘Land’ elevation value. A ‘Land’ value is specified in the .dsf2 grid file that specifies a value at which elevations equal to or greater than this value are considered ‘Land’ and will not be subject to possible wetting and drying. This value could be used as a guidance for producing a TUFLOW code layer. The steps in identifying this value are as follows:
<ol>
<li> Open the MIKE Zero program
<li> Open the .dfs2 file through <b>Open</b> (or drag and drop)
<li> From the toolbar select <b>Edit</b> >> <b>Custom Blocks…</b>
<li> The fourth element value is the ‘Land’ value elevation<br>[[File: MikeZero-Edit-CustomBlocks.PNG|350px|]]
</ol>
''Note: A downfall of this method in MIKE, is that elevations in the .dfs2 grid could have been modified such that the area outside the flood extent has been set at a constant ‘Land’ elevation. Inspection of the terrain data before use is highly recommended. ''
