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>!

The location of source boundaries can be found in the MIKE21 control file (.m21) in the <b>Basic Parameters</b> >> <b>Source and Sink</b> tab. The location of the boundaries are specified as a point object using the local (j, k) coordinate system. These are required to be converted to absolute coordinates so an identical boundary location can be digitised in TUFLOW. The conversion process can be undertaken using identical steps as performed with converting upstream and downstream boundaries.
It is recommended that the source boundary point from MIKE be converted to a 2d_SA polygon in TUFLOW. The 2d_SA polygon should be enlarged to encompass a larger region such that it is able to apply flow to more than one cell. This is considered to give a more stable and accurate representation of flow distribution to the model. More information on how 2d_SA polygons distributes flow can be found in the <u>[https://
The name of the boundary can be found from <B>Hydrodynamic Parameters</b> >> <b>Source and Sink</b> tab.<br>[[File: MIKE21-HP-Source-Names.PNG|750px|]]

The location of the 1D / 2D boundaries can be found in the MIKE Flood control file (.couple) under the <b>Link Definitions</b> tab. The (X, Y) coordinates specify the vertices of a polyline that can be digitised in TUFLOW using either ‘SX’ or ‘HX’ connections. Link Type <b>Standard</b> is similar to 'SX' connections, <b>Lateral</b> to 'HX' connections and <b>River/Urban</b> is for connections from Mike Urban package.<br>[[File: MIKEFlood-Linkages.PNG|750px|]]

The time series will need to be formatted so that the time column units are in hours. This can be done in MS Excel or equivalent. More information on setting up inflow boundaries can be found in the <u>[https://

Water Level Lines can also be used to view the 1D results in the 2D mapping. For more explanation on Water Level Lines, please see the <u>[https://

<li> You can obtain the start and end dates from this tab which need to be converted to hours for TUFLOW (in the screenshot below, the simulation duration is 3 hours)<br>[[File: MIKE21-Simulation-Period.PNG]]

The 2D timestep should be set to an appropriate TUFLOW interval and not be copied directly from the MIKE21 model. It also up to the user to consider output types and time series Plot Output (PO) locations. More information on appropriate timestep intervals and map output types can be found in the <u>[https://
