= TUFLOW Control File (TCF) =
Finally, the TCF is updated as follows:
:*Remove references to model parameters that are read from Flood Modeller.
:*Read in the GIS layer of the Flood Modeller nodes.
:*Read in the GIS layers used to create Water Level Lines along the Flood Modeller component of the model (optional).
:*Add a reference to the ESTRY Control File.
:*Update references to the TBC and TGC.
The following steps outline how to apply these updates:<ol>
<br>
<ol>
<li> In the \FMT_Tutorial\FMT_M01\TUFLOW\runs folder, save a copy of the TUFLOW file created as a part of [[Tutorial_M02 |Module 2]] ('''M02_5m_001.tcf''') as '''FMT_M01_001.tcf'''. </li>
<li> In a linked Flood Modeller - TUFLOW model,Remove the Start Time, End Time, and 2D Timestep parameters from the TCF, as these are read from the Flood Modeller .ief file. Itin isa bestlinked practiceFlood to therefore removeModeller-TUFLOW thesemodel. parameters from the tcf.</li><li> AndAdd an exclamation mark in front of each of the belowfollowing commands.<br><font color="green"><tt>!
