=Introduction=
This utility performs a variety of operations on the TUFLOW 2D outputs. Valid formats are .xmdf (as of utility version 2012-10-AC) and .dat files. This page is split into two section, utility operations (e.g. maximum, difference etc.) and general options. The general options can be used regardless of operation being performed. The table of contents can be used to jump to a desired operation.
Line 11 ⟶ 10:
This can be used to extract the maximum from a number of input datasets. Any number of input files can be specified. If a maximum folder exists in an .xmdf file for the type specified, this dataset will be used, for dat files use -t99999 to use the maximum data in the .dat file.<br>
<u>Examples</u><br>
▲<ol>
<li>Extracts the maximum water level from the three .
<li>When maximums are tracked over all timesteps, extracts the maximum water level from the maximums output.<br>

==Min==
'''Input Switch: -min'''<br>

<u>Description</u><br>
This can be used to extract the minimums from a number of input datasets. Any number of input files can be specified. If a minimum folder exists in an .xmdf file for the type specified, this dataset will be used.<br>

<ol>
<li>Extracts the minimum water level from the three
<tt>res_to_res.exe -min -typeH -out Minimums.xmdf results_1.xmdf results_2.xmdf results_3.xmdf</tt>

==Difference==
'''Input Switch: -dif'''<br>
<u>Description</u><br>
This can be used to compare two datasets. If a third file is specified, the third file is used as the output file. The output filename can also be specified with the -out option. The output is the first
A special wet/dry algorithm is used. If water level results are not specified (_h.dat or -typeH), the algorithm opens these files, as well as opens the .2dm file associated with the results files, and uses the water levels and ZH Zpt values (for 2D cells) and elevations at the WLL triangle corners to determine whether a node (corner of

==Duration==
Line 48 ⟶ 51:
Determines the duration in hours that the the results exceed the cut off value.<br>
'''Note: ''' A preferable approach is to use the .tcf file command: <tt>Time Output Cutoff Depths == <cut off value or values></tt>. With this command specified TUFLOW tracks this on a timestep by timestep basis rather than post processing this at the map output interval.<br>

<li>Converts all times in the .dat file into xmdf file format.<br>
</ol>
==Time of Increase==
'''Input Switch: -toi<cutoff>'''<br>
Calculates the time taken for the results to increase by the cutoff. For example if a value of 0.2 is used for a depth grid, the output result contains the time required for the depth to increase by 0.2m. If there are depth values greater than 0.2 initially (due to initial water level conditions), the output is the time for the depth to increase by 0.2m. For dry areas it is the time for the depth to reach 0.2m.<br>

<li>Extracts the time taken for the depth to increase by 0.2m.<br>

=General Options=
Line 170 ⟶ 193:
When working with the .xmdf outputs from TUFLOW, there are some additional input switches are available. This is because the .xmdf file uses a folder structure and multiple output parameters are stored in the same .xmdf file. When converting you can control which dataset is converted using the switches below. These switches are not valid for .dat files as these contain a single parameter for each file. E.g. the _d.dat contains only depth information.<br>
In the xmdf file, the data is stored in the following structure:<br>
<tt>Simulation ID/Folder/Dataset</tt>. Some examples for simulation "

The xmdf specific switches are outlined in the table below:<br>
Line 179 ⟶ 202:
! width=80% | Description
|-
|"-type<output type>"|| Converts the specified output type in an xmdf file. Output types should be specified as per the output type in the .tcf e.g. h (water level), v (velocity), q (unit flow) or d (depth). Output types other than h, v, q and d are not predefined with the -type switch and should be called with -v and/or -s switch.
|-
|"-s<output id(integer)>"|| Converts the specified scalar dataset in an xmdf file. For example, <tt>-s1</tt> will convert the first scalar dataset. A list of the available datasets is listed within the
|-
|"-v<output id(integer)>"|| Converts the specified vector dataset in an xmdf file. For example, <tt>-v1</tt> will convert the first vector dataset. A list of the available datasets is listed within the
|-
|"-Folder<Folder Name>"|| Converts all datasets within a particular xmdf file. For example, <tt>-Folder"Maximums"</tt> will convert all datasets in the \Maximums\ folder.
|-
|"-path<path name>"||Converts a dataset based on the path in the .xmdf file. For example, <tt>-path"Maximums/ZAEM1"</tt> would convert the dataset Maximum ZAEM1 dataset. This can be a full path in the .xmdf file or a partial match. E.g.:<br>
<tt>-path"Maximums/ZAEM1"
<tt>-path"
|}
==XMDF Dataset Example==
Display the datasets available within an XMDF file in a console window by starting any operation. <br>
To keep the console window open write "pause" at the end of the processing batch file and ensure -b switch is not included. <br>
The list of available datasets will be displayed towards the start of the console window. <br><br>
<tt>res_to_res.exe -xnfo results.xmdf<br>
pause</tt><br><br>
Displays the following console window: <br>
