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.
The section below contains a list of the operations that the utility can perform. One of these operations must be specified or the utility will generate an error.
Input Switch: -max
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.
Extracts the maximum water level from the three .dat files, where the maximum water level over all timesteps (tracked and output to t99999) is available for each of the .dat files.
As above but for results stored in xmdf file format.
Extracts the maximum water level of all available output times for a .dat file. Note this does not provide the true, tracked maximum over all timesteps.
Input Switch: -min
This option was added in the 2015-02-AA version of the utility. If using an earlier version this command will not be recognised as valid.
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.
Extracts the minimum water level from the three .dat files.
As above but for results stored in xmdf file format in "Minimums.xmdf".
Input Switch: -dif
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 result minus the second result file.
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 a mesh element) is wet or dry. This allows two special values to be output in the event that a node is dry in one results file and wet in the other or vice versa. A value of -99 is used to indicate that a node is dry in the first results file, but is flooded in the second results file, while +99 indicates that the node was wet in the first results file but is dry in the second results file. Specifying -nowetdry does not carry out a wet/dry check using the water level results.
The -t option can be used to carry out the difference at a particular time (rather than all times). The most common time is to take the difference at the flood peak, ie. specify -t99999.
Extracts the difference in water level, the output is results_developed_h - results_existing_h for all timesteps.
Extracts the difference in water level for the maximum water level and suppresses the wet/dry check described above.
Input Switch: -dur<cut of value>
Determines the duration in hours that the the results exceed the cut off value.
Note: A preferable approach is to use the .tcf file command: Time Output Cutoff Depths == <cut off value or values>. With this command specified TUFLOW tracks this on a timestep by timestep basis rather than post processing this at the map output interval.
Extracts the duration in flooding above 0.1m deep.
Input Switch: -k<output time>
Can be used to extract a single timestep from a results file. This is useful to extract the maximums to a separate file making it easier to transfer electronically. To keep a range of output times see the -range option below.
Creates a new results file containing just the maximum from the water level results.
Creates a new results file containing just velocity results for the 2.5 hour output.
Input Switch: -rangeA<start time> -rangeB<end time>
Extracts all timestep between start time and end time (inclusive) into a separate results file.
Creates a new results file containing the outputs between 1.0 and 2.5 hours. Both 1 and 2.5 hour outputs are included.
As above but for xmdf input files.
Input Switch: -r<output time>
Creates a new output file and removes the output time from this.
Creates a new output file which does not include the output at 3.
Input Switch: -trim<value>
Creates a new output file which has any values above <value> set to <value>. If the input is a vector data, the vector magnitude is used to trim the value (direction is unchanged).
Creates a new output of velocity with any outputs greater than 5.0 set to 5.0.
Input Switch: -times
Creates a text file which contains the output times in the .dat or xmdf file. If no output filename is specified with the -out option the output file will be called "times.txt". For xmdf files see also the -xnfo option below.
Creates an an output file "times.txt" which contains all timesteps that are contained in the results file.
Input Switch: -xnfo
Creates a text file which contains a list of the datasets contained within the .xmdf file. The number of output times and the output times are also exported to the text file.
Creates an an output file with the specified filename "xmdf_info.txt", which contains information about the contents of the xmdf file.
Input Switch: -va
Outputs the vector direction in degrees relative to north (North = 0°, East = 90°, South = 180°/-180°, West = -90°).
Outputs the velocity direction for all timesteps in the results_v_va.dat file.
Input Switch: -con
Concatenates (joins) two or more results files into one. Each results file must be from the same 1D/2D mesh.
Joins the three files into a single .dat file.
Joins the water level results contained in the .xmdf files into a single
Input Switch: -conv
Converts between .dat and .xmdf format results. Not to be confused with -con (concatenate option described above)!
Converts the maximum water level results in the xmdf file into .dat file format.
Converts all datasets and times in the .xmdf file into .dat file format. This will output a number of .dat files.
Converts all times in the .dat file into xmdf file format.
Time of Increase
Input Switch: -toi<cutoff>
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.
Extracts the time taken for the depth to increase by 0.2m
Input Switch: -ensight
Converts an .xmdf file (.dat not yet supported) into Ensight Gold format.
If the input dataset is corner based (standard output) the Ensight results are output as scalar / vector per node (cell and triangle corners).
If the result is high resolution (Map Output Format == xmdf high res) then the Ensight results are per element. For 2D cells this is based on the cell centre output, for triangles (1D water level lines) this is based on an interpolation of the triangle vertices. The conversion produces the following output files:
- Ensight case file;
- Ensight geometry file;
- Ensight results as either per node or per element depending on the input file.
This conversion is in its beta stage of development. This utility can currently only process 2D results. 1D channel result are currently not supported.
Any feedback regarding this utility function is welcome and can be sent to email@example.com.
Converts all datasets in the xmdf file into Ensight format.
Input Switch: -b
Batch mode suppresses prompt to press Enter at end of processing. Used in .bat files where two or more files are to be processed in succession.
Input Switch: -out "output_filename"
Sets the output filename. This is not available for all outputs, particularly where multiple output files are required!
Time Search Tolerance
Input Switch: -dttol<search tolerance>
Allows the user to specify the time search tolerance. This is particularly useful for TUFLOW FV model results, as model uses an adaptive timestep the output time might not exactly match the desired output interval. If hourly output is requested the closest output might actually be 01:00:05 (HH:MM:SS). If extracting results at time 1, the requested time may not be found due to time search tolerance. The default value is 0.001.
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.
In the xmdf file, the data is stored in the following structure:
Simulation ID/Folder/Dataset. Some examples for simulation "M01_5m_013_SA_CPU" are:
The xmdf specific switches are outlined in the table below:
|"-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 (flow) or d (depth).|
|"-s<output id(integer)>"||Converts the specified scalar dataset in an xmdf file. For example, -s1 will convert the first scalar dataset. A list of the available datasets is listed within the DOS window when RES_to_RES is preprocessing results.|
|"-v<output id(integer)>"||Converts the specified vector dataset in an xmdf file. For example, -v1 will convert the first vector dataset. A list of the available datasets is listed within the DOS window when RES_to_RES is preprocessing results.|
|"-Folder<Folder Name>"||Converts all datasets within a particular xmdf file. For example, -Folder"Maximums" will convert all datasets in the \Maximums\ folder.|
|"-path<path name>"||Converts a dataset based on the path in the .xmdf file. For example, -path"Maximums/ZAEM1" would convert the dataset Maximum ZAEM1 dataset. This can be a full path in the .xmdf file or a partial match. E.g.:|
