==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>!

Grid rotation in the MIKE model can be determined using the following steps:
==TUFLOW Code Layer==▼
The user can manually set the TUFLOW code layer by viewing the terrain data through their preferred GIS program. MIKE also uses a process of defining active cells by specifying a ‘Land’ elevation value. A ‘Land’ elevation value is defined 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 elevation grid through <b>Open</b> (or drag and drop)
<li> From the toolbar select <b>Edit</b> >> <b>Custom Blocks…</b>
<li> The

<br>More information on setting the model domain extent and rotation is provided in Section 6.5 of the <u>[https://www.tuflow.com/Download/TUFLOW/Releases/2016-03/TUFLOW%20Manual.2016-03.pdf TUFLOW Manual]</u>.

Following the same steps as above in
''Note: A downfall of this method in MIKE, is that elevations in the .dfs2 grid may have been manually modified such that the area outside the flood extent has a constant ‘Land’ elevation. Inspection of the terrain data before use is highly recommended. ''
