==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 <b>Read Grid Location</b> command.<br><br><font color='green'><tt>! Set model domain</tt></font><br><font color='blue'><tt>Read Grid Location</tt></font> <font color='red'><tt>==</tt></font> <tt>..\model\grid\example_grid.asc</tt><br><br>Because the grid rotation is taken from the origin (lower left corner) of the domain, the resulting domain extent can end up unsuitable, as demonstrated by the image below (using a rotation of just 20 degrees). The <b>Read Grid Location</b> command is therefore best suited if there is no grid rotation, and other command methods used when grid rotation is needed.<br><b>LEFT: Rotation about Grid origin. RIGHT: Rotation about manually set Origin</b><br>[[File: Domain-rotation-atorigin-comparison.PNG|750px]]
Grid rotation in the MIKE model can be determined using the following steps:

===TUFLOW Commands===
The Domain in TUFLOW can now be set up in the TGC. Below is an example of how the Domain could be created, however there are several methods that could be used. The domain should always be checked by viewing the <b>dom_check</b> file. Be careful when translating a rotation from MIKE to TUFLOW, as they process the origin slightly differently.<br><br><font color='green'><tt>!
