<br>The <tt><font color="blue">Create TIN Zpts WRITE TIN</font></tt> command creates and writes a .2dm mesh file to the same location as the GIS layer (in this case the TUFLOW\model\gis folder). The .2dm TIN can be viewed, checked, and modified in QGIS. It can then be read into the model directly using the <tt>Read TIN Zpts</tt> command for subsequent model simulations.

<li>We have also created a new bc_dbase in this module which will need to be referenced. Update the command as follows:
:<font color="blue"><tt>BC Database</tt></font><font color="red"><tt> ==</tt></font> ..\bc_dbase\bc_dbase_FMT_M02.csv
<li>We are using an updated GIS layer for the Flood Modeller Nodes. Update the command as follows:

From the <b>TUFLOW\check\2d\</b> folder open within QGIS:
*FMT_M02_001_1d_to_2d_check
*FMT_M02_001_sac_check
 
The _1d_to_2d_check layer highlights the location of all 1D/2D boundary links within the model. Where we have digitised the pipe network, this check file shows the SX boundaries that have been created at the location of the pits. This check file also shows the ZC elevation of the SX boundary which can be compared to surrounding ZC elevations by viewing alongside the grd_check layer. The check layer also shows the HX boundaries digitised along the river banks in Module 01.

The 1D ESTRY results can be viewed by opening the time series results using the approach described in the following page: [[TUFLOW Viewer - Load Results - Time Series]]. You can also open results from Flood Modeller within the TUFLOW Viewer using htethe instructions here: [[TUFLOW Viewer - Load Results - Time Series FM]]
 
It can be seen that there is negative flow in Pipe16 and Pipe18 when the water levels in the Flood Modeller node and the connected ESTRY nodes are such that backwater effects are present.
