=Introduction=
Often, there is a requirement to convert aspects of a Flood Modeller model to a TUFLOW ESTRY model. It is possible to convert a Flood Modeller 1D model to a TUFLOW ESTRY format using either the fm_to_estry.exe or fm_to_estry.py utilities. The utilities are available for download from the <u>[https://gitlab.com/tuflow-user-group/tuflow/model-conversions/fm-to-estry TUFLOW Gitlab User Group]</u>. This Wiki page lists useful examples for using the fm_to_estry.exe and fm_to_estry.py utilities.<br><br>If you have any suggestions to be included in these pages, please email

In order to convert a Flood Modeller network to ESTRY using the fm_to_estry executable follow the instructions below.
<ol>
<li>Download the
<li>Open the file. Then, bring in the relevant files from the Flood Modeller model that requires conversion, in this example the .<b>dat</b>, .<b>gxy</b> and projection files. The projection.<b>shp</b> file will help you to assign your model to the correct projection and can come from an existing TUFLOW model or shapefile in the correct projection. See figure below for the required files:<br>[[File:Fm2estry_1.png|300px|]]
<li>Create a new .bat file (To do that right click in an empty area in the file. A dialogue will open. Choose New and then Text document. Rename your new Text document by including the <b>.bat extension</b> at the end. For Example: fm_to_estry_example.<b>bat</b>).

Converts a Flood Modeller model
<li><pre>fm_to_estry.exe flood_modeller.gxy flood_modeller.dat -crs "EPSG:32760"</pre>
Uses an EPSG number (32760) for the projection
<li><pre>fm_to_estry.exe flood_modeller.gxy flood_modeller.dat -crs projection.shp -out .\output</pre>

It is also possible to use the cross-sections from the Flood Modeller <b>.dat</b> file directly within a TUFLOW/ESTRY simulation. This means that for some simpler models, particularly those without structures, that conversion of the Flood Modeller model to an ESTRY format is not required with the cross-section data being used in a TUFLOW 1D /ESTRY model directly from the <b>.dat</b> file. Please, see the [https://docs.tuflow.com/classic-hpc/manual/2023-03/ECFCommands-1.html#ecfXSDatabase <font color="blue"><tt>XS Database</tt></font> <font color="red"><tt>==</tt></font> command] in the [https://docs.tuflow.com/classic-hpc/manual/latest/ TUFLOW user manual] for more information
=Summary=
When there is a requirement to convert a Flood Modeller 1D network, or part of a network, to TUFLOW ESTRY format this can be time consuming. A set of tools have been provided for you to assist this process. Currently, the tools are restricted to network geometry but if there is user-demand, this can be extended to boundary conditions, logical rules and the production of TUFLOW control files. There are two approaches, using either an executable or a Python tool, both of which undertake the same conversion. The advantage of the Python tool is that it is possible to add user-specified support for additional structures which are not supported currently. Once the Flood Modeller network has been converted to a set of ESTRY layers, these should be checked for connectivity and brought together in the ESTRY Control File to read into a TUFLOW
