UltraEdit Colour Coding

2015-10-02T01:23:18Z

David Sturgeon-Smith:

= Introduction =

This page describes the process for setting up TUFLOW control file colour coding. The method for enabling this has changed slightly with UltraEdit versions, an releases pre version 15 used a '''wordfile.txt''', version 15 and onward use a '''TUFLOW.uew'''. The process is described for both of these methods.

=Method=
==Current UltraEdit (version 15 onwards)==
Download "TUFLOW.uew" file from the TUFLOW website, available at [http://tuflow.com/Download/Miscellaneous/TUFLOW.UEW.zip http://tuflow.com/Download/Miscellaneous/TUFLOW.UEW.zip]. Save this file to the UltraEdit Wordfile Directory. The default directory varies depending on the version of UltraEdit and Username. To check where this directory is (or to change this directory) use the following menu item: 
:''Advanced >> Configuration >> Editor Display >> Syntax Highlighting'' 
Once the file has been added to the directory, you may need to restart UltraEdit to see the changes. 
[[File:UE Syntax Highlighting uew.png|frame|none|UltraEdit Syntax Highlighting, set Wordfiles Directory]]

==Older Versions (pre version 15)==
Use the automatic colour coding of the control files by downloading the “WORDFILE.TXT” file available at [http://www.tuflow.com/Downloads_Misc.htm www.tuflow.com/Downloads_Misc.htm] and replacing the file with the same name in the C:\Program Files\UltraEdit folder. Alternatively, in later versions of UltraEdit a path can be specified to the WORDFILE.TXT file as shown in the UltraEdit Configuration dialogue below: 
Once the file has been added to the directory, you may need to restart UltraEdit to see the changes. 
[[File:UE Syntax Highlighting txt.png|frame|none|UltraEdit Wordfile.txt Configuration]]

=Example=
Once implemented, TUFLOW control files (tcf, tgc, ecf, tbc and others) should now be colour coded like the example below:
[[File:UE Example ColourCoding.png|frame|none|Example Colour Coding]]

= NT Batch and DOS Syntax Highlighting =
If you are regularly setting up and running TUFLOW from DOS batch files, the following wordfile may also be of use to you:
[http://www.ultraedit.com/files/wf/dosntbatch.uew http://www.ultraedit.com/files/wf/dosntbatch.uew]

It can be loaded using similar methods to that of the TUFLOW wordfile in the examples above.

SMS 3D Animation

2013-10-25T00:33:42Z

David Sturgeon-Smith: /* Creating a 3D Animation */

<ol>
==Introduction==
This page explains how to make a 3D animation using the SMS software. SMS version 11.0 has been used for this example, however good results can also be achieved using older versions of SMS. As a minimum you will need a licence for the SMS VIZ edition (see [http://www.aquaveo.com/sms-pricing SMS pricing)].
 
==Data Required==
As a minimum you will need: 
* Digital Elevation Model/TIN;
* Aerial Photography; and
* 2D Model Results.
Together with aerial photography, the 2D results for Tutorial Module 3 are used here. The complete model is available from the Downloads section of the [http://www.tuflow.com/ TUFLOW website].
 
==Creating a 3D Animation==
The 2D results include the ground elevation (.2dm), water level (_h), depth (_d) and velocity (_v) datasets. The following steps may equally be followed using other datasets you may have.

<li>Begin by opening in SMS the ground elevation (.2dm) and 2D results datasets using the '''M03_5m_001.ALL.sup''' results file located in the '''TUFLOW\results\M03\2d''' folder, together with the aerial photography '''Aerial_Photo_M01.jpg''' available in the '''Module_Data\Aerial_Photos\SMS''' folder.
SMS should now look something like this: 
 
[[File:SMS 3D AVI 1.jpg|600px]]
 
</li>
 
<li>To view the 2D mesh at a pseudo-3D oblique view, open the ''Display Options >> 2D Mesh'' window and check the Elements on. Using the Rotate tool [[File:SMS Rotate Icon.png]] you can drag the map view and change to an oblique view. 
 
[[File:SMS 3D AVI 2.png|600px]]</li>
 
<li>Return to ''Display Options >> 2D Mesh'' and uncheck Elements. To display imagery draped over a 3D surface we need to turn on Texture Mapping. Go to ''Display Options >> General'' and select '''2D Mesh''' under the Texture Mapping Display Location list.
Selecting 2D Mesh uses the TUFLOW model ground elevations contained in the .2dm file as the 3D surface over which imagery is draped. The Scatter Set option may be used to drape imagery over an active scatter set TIN.
The General options include the ability to exaggerate the Z axis scale by changing the Z magnification. Uncheck '''Auto z-mag''' and change the '''Z magnification''' to a factor of 5.0. Rotate the map view and SMS should now look something like this: 
 
[[File:SMS 3D AVI 3.png|600px]]</li>
 
<li>Turning Contours on in the display options drapes the active dataset over the terrain. This can however look somewhat strange because an animation will show the water surface rising and falling according to the underlying terrain. A useful feature in SMS is to define one dataset as a functional surface, over which a second dataset other than the terrain may be draped. This allows, for example, water depth to be draped over the water surface rather than the terrain, giving a more realistic 3D impression of the water surface and varying depth.
 
To enable a functional surface, go to ''Display Options >> 2D Mesh'', uncheck '''Contours''', check '''Functional Surface''' and select Options.</li>
<li>Under Data Set, select '''User defined dataset''' and select your water surface (_h) dataset.</li>
<li>Under Display Attributes, select '''Contour surface''' and check '''Specify separate dataset for contours''' and select your water depth (_d) dataset. This instructs SMS to drape the water depth contours over the water surface, which will provide a realistic view of the water surface and the depth of water above the terrain. 
 
[[File:SMS 3D AVI 4.png]]</li>
 
<li>Under Contour surface, select Options to view the Dataset Colour Options. Use this window to customise the display options of the water depth. This example makes use of '''SMS Palettes.pal''' colour palette available from the Downloads section of the [http://www.tuflow.com/ TUFLOW website]. Located in the '''Colour Ramp''' options, the '''Depths''' colour palette is loaded using the '''User defined''' method. 
 
[[File:SMS 3D AVI 5.png|350]]
[[File:SMS 3D AVI 6.png|250]]</li>
 
<li>Change the '''Colour Interval''' to the number of colours you'd like and check '''Specify a range''' that increases the colour range for overland (more shallow) flood depths. Enable transparency by changing the '''Transparency''' to 40%. If you haven't already, turn on '''Vectors''' in the ''Display Options >> 2D Mesh'' window. 
 
[[File:SMS 3D AVI 7.png|600px]] 
 
SMS should now look something like this: 
 
[[File:SMS 3D AVI 8.png|600px]] 
 
By using the functional surface option, the depth contours are now draped over the water surface and not the terrain.</li>
<li>Another option is to enable relief shading to emulate hill shade. If you wish to enable this option, you may do so under the ''Display Options >> General'' menu and '''Shading''' tab. Check '''Enable lights''' and configure the settings as you prefer. 
 
[[File:SMS 3D AVI 9.png|600px]]</li>
 
<li>Finalise your map view by customising the ''Display Options >> 2D Mesh >>'' '''Contours''' tab display options and legend, together with your angle of view using the Rotate tool. It's a good idea to step through your 2D results timesteps to ensure you're happy with how the animation will appear.</li>
<li>You're now ready to create the animation. Open the ''Data >> Film Loop'' menu to create the animation. If you're unsure about this, you may follow the steps provided in the Animations section of the [[SMS_Tips#Animations | SMS Tips]] page.</li>
<li>You may create animations using any view that you wish, depending on any particular features in your results that you wish to show. 
 
[[File:SMS 3D AVI 10.png|600px]]
[[File:SMS 3D AVI 11.png|600px]]</li>

The SMS installation includes the avi viewer "pavia.exe", this viewer allows the speed (frame rate) of the created animation to be set. 
Have a play around with the various options, as there is too much to cover in this page!

TUFLOW Utilities

2013-09-06T05:31:03Z

David Sturgeon-Smith: /* MapInfo Utilities */

=Introduction=
A number of utilities are available on the the TUFLOW website (http://www.tuflow.com/Downloads_Utilities.htm Download TUFLOW utilities]). Many of the utilities are DOS executables and run without a graphical user interface, like the TUFLOW engine itself. There are also some excel macros and the MapInfo tools, which are MapBasic applications designed for MapInfo.

These utilities are described individually in the page linked below.

=DOS Utilities=

==Running DOS utilities==
As with TUFLOW there are multiple methods for running the DOS executables. The most common methods are from a batch file and using the right mouse button on the input file.
===From a Batch File (.bat)===
Where there is more than one input file then a batch (.bat) file needs to be created. Batch files are also powerful when you want to bulk process data. These are simply a text file containing one or more lines that execute a utility as per the examples given in the examples sections of each utility. To execute the .bat file, double click on the file in Windows Explorer. To force the .bat file to pause at the end (and not simply disappear off the screen), enter the text “pause” on the last line of the file.
===Using the Right Mouse Button in Windows===
The right mouse button functionality is only suited to operations that only require one file as an input. For example these method can be TUFLOW_to_GIS to create a 3D surface of the results. However, it would not be suitable for using dat_to_dat to calculate the difference between files.
==List of DOS Utilities==
*[[TUFLOW_to_GIS | TUFLOW_to_GIS.exe]]
*[[DAT_to_DAT |DAT_to_DAT.exe]] (superseded with [[RES_to_RES |RES_to_RES.exe]])
*[[RES_to_RES |RES_to_RES.exe]]
*[[ASC_to_ASC | ASC_to_ASC.exe]]
*[[Convert_to_TS1 | Convert_to_TS1.exe]]
*[[TIN_to_TIN | TIN_to_TIN.exe]]
*[[xsGenerator | xsGenerator.exe]]
*[[12da_to_from_mif | 12da_to_from_mif.exe]]

=Excel Utilities=
Please see the [[Excel_Tips | Excel Tips]] for a description of the TUFLOW Tools for Excel.

=MapInfo Utilities=
The miTools are a series of MapBasic utilities that are designed for making the creation and review of TUFLOW modellers more efficient in MapInfo. For more information on the miTools please see the TUFLOW website [http://www.tuflow.com/miTools.aspx here]. 
Alternatively, queries on the miTools can be directed to miTools@tuflow.com.

Check 2098 Could not find a SC connection snapped to SH boundary

2012-09-05T02:02:30Z

David Sturgeon-Smith: Created page with "==Error Message== When reviewing the TUFLOW messages I get the following check message: * CHECK 2098 - Could not find a SC connection snapped to SH boundary. ==Reason== This usu..."

==Error Message==
When reviewing the TUFLOW messages I get the following check message:
* CHECK 2098 - Could not find a SC connection snapped to SH boundary.
==Reason==
This usually occurs because the objects are not snapped together in the 2d_bc layers(s). If you were using a pump to discharge water out of the catchment e.g. for flood relief pumping, it is common to not have a connection object for the pump because you are not modelling where the pumped water is moved to. However, in Module 14 the pump is transferring water to a location within our 2D model domain. Therefore we do in this instance require a connecting object to transfer the pumped water. 
 
The '''SH''' boundary object (the pump) needs to be snapped to the end of the '''SC''' connection line, allowing the transfer of pumped flow to the new location in our 2D domain. The connectivity between the layers and objects is based on their snapping. Where these features are not snapped, Check 2098 will occur with flow in or out of the SH boundary lost, adding to model mass error.
==Solution==
To locate where the problem is occurring, import or load the '''_messages''' layer into your GIS package. This file is saved in the log directory. In the tutorial model this is '''TUFLOW\runs\log\''' and will have the same name as the TUFLOW simulation. In Module 14 the messages layer is called either:
* M14_5m_001_messages.mif (GIS FORMAT == MIF); or
* M14_5m_001_messages_P.shp (GIS FORMAT == SHP).

This GIS layer contains information on where the error is occurring and is viewed by zooming to the message. 
:'''Tip:''' the zoom to layer extent function in your GIS package can help here. 

You may need to zoom in very closely to the area but the SH and SC objects will not be correctly snapped. To overcome the problem: 
'''For MapInfo users:''' 
Ensure that the "snap tool" is enabled and the layer you are snapping to is selectable. The "Reshape" option can be used to move a vertex. 
'''For QGIS users:''' 
Ensure the layer you are snapping to has snapping enabled (see the ''Settings >> Snapping Options...'' menu) and an appropriate snap tolerance is specified (5-10 map units/metres). The "Node Tool" may be used to move vertices.
==Additional Information==
The following .tcf file command may also be used to set the snap tolerance in TUFLOW. The default is 0.001 metres (1mm). 
<tt>Snap Tolerance </tt> <tt>==</tt><tt> <value in metres></tt>
