TUFLOW July 2009 Release Notes
Brief descriptions of each build for the July 2009 releases are provided below. Please note that the new features in the 2009-07 release are documented in July 2009 Release Notes (pdf). A 2009 update to the TUFLOW manual will be provided with a second 2009 TUFLOW release later in the year.
New builds are provided in the event of any bug fixes or minor enhancements, and recognition of new dongles. It is recommended to always use the latest build. Emails of new builds are sent out to all registered members of the TUFLOW Forum who have elected to receive email notifications (to register for the forum click here).
Build 2009-07-AE: December 5, 2009 (Bug fix and enhancements - mandatory upgrade)
Build 2009-07-AD: October 22, 2009 (Minor enhancements and bug fixes)
Build 2009-07-AC: September 25, 2009 (Same as 2009-07-AB but recognises new SMS 10.1 TUFLOW licensing)
Build 2009-07-AB: September 21, 2009 (ISIS compatibility for iSP and iDP; Minor bug fixes)
Build 2009-07-AA: August 9, 2009 (First release - also see July 2009 Release Notes (pdf))
Build 2009-07-AE : December 5, 2009 (top)
Build 2009-07-AE includes the following enhancements and bug fix. To download visit TUFLOW Executables.
1. Fixed bug that caused problems in model startup where W channels existed. Only known occurrence of this bug caused “ERROR 2050 - Lowest ZC elevation at/along SX link is above 1D node bed.” at W pits, but the bug is such that it may be possible to cause other problems/errors. This bug is from a new feature built into Release 2009-07 and does not effect releases prior to 2009-07.
2. Map Output .dat files now closed prior to writing to “_ TUFLOW Simulations.log” files to ensure that they are closed off properly in case there are problems across the network when writing to the .log files.
3. The 2d_bc “a” attribute for HX lines is now used for assigning additional energy losses (FLC) along HX lines. This may be useful for 1D/2D models where additional energy losses are needed to "calibrate" the flow from a river (1D) onto the floodplain (2D). Alternatively the .tgc “Read MI FLC ==” command can be used. Note, that to ensure backward compatibility the “a” attribute must be set to zero (0.0) for HX lines.
4. The maximum number of polygons within one region object has been increased from 1,000 to 10,000.
Build 2009-07-AD : October 22, 2009 (top)
Build 2009-07-AD is computationally identical to prior 2009-07 builds. It includes the following enhancements and bug fixes. To download visit TUFLOW Executables.
1. Fixed bug that occurred in multiple 2D domain models with pits being located in both domains. In some instances the pit connection was placed in the wrong location if it had already been allocated to a prior 2D domain, and would try to connect the pit a second time. If this occurred the simulation startup would stop with an ERROR 2056.
2. New "Map Output Data Types ==" options of ZMW1 and ZMW2 representing the old (ZMW1) and current (ZMW2) flood hazard categories required for Melbourne Water studies. These will be documented in the next release of the TUFLOW manual, but in the interim please contact support@tuflow.com if you require details.
3. Fixed bug that didn’t find column labels in .csv files when the label in the .csv file was surrounded by quotes. If exporting the .csv file from Excel, Excel doesn't include quotes around the label (unless the label has a double quote in it), in which case this bug didn't occur. If the label does have quotes around it due to being produced by software other than Excel, TUFLOW would stop with an error that the column label could not be found. From this build onwards when searching for labels, or any other string comparisons, all quotes, single and double, are now removed prior to making the comparison.
4. If "Set IWL ==" in the .tcf file was specified without using "==" this would ignore any subsequent IWL, PO, FC and GLO commands. This is now fixed.
5. The time for minimums output in the _Times.dat file has been set to 910001. It was previously -1.
6. A file "Projection.mif" is now written to the 2D output folder and will be used by the latest TUFLOW_to_GIS (Build 2009-10-AB). This saves the need to create a Header.mif file (a Header.mif file is still recognised by TUFLOW_to_GIS if it exists).
Build 2009-07-AC : September 25, 2009 (top)
Build 2009-07-AC is identical to 2009-07-AB but recognises the new SMS 10.1 TUFLOW model licensing. For SMS 10.1 users, this build is that shipped with the first SMS 10.1 release. Those using SMS 10.0 should not download this or later TUFLOW builds. For non-SMS TUFLOW licensing either 2009-07-AB or AC can be used. To download visit TUFLOW Executables.
Build 2009-07-AB : September 21, 2009 (top)
Build 2009-07-AB includes the following enhancements and bug fixes. To download visit TUFLOW Executables.
1. This build (for both single and double precision builds) is compatible with future releases of ISIS. ISIS-TUFLOW users will need to upgrade to the new version of ISIS. Note, up until this build, only single precision TUFLOW builds were compatible with ISIS.
2. The CPU time to the start and end of the simulation has been added to the "_ TUFLOW Simulations.log" files.
3. Fixed bug that crashed TUFLOW if the new Evacuation Route Categories feature was run with maximums being tracked.
4. Fixed bug that did not correctly write out minimums at end of simulation.
5. Added in WARNING if skew angle on a cross-section exceeds 89.9 degrees. If the skew angle is set to 90, the cross-section is effectively blocked and has zero area and wetted perimeter. Skew must be in the range from -89.9 to 89.9 with a value of zero meaning the flow is perpendicular to the cross-section and there is no adjustment to the hydraulic properties. For example, a skew of 60 would reduce the cross-section area and widths by 50%. If the absolute values of the skew in this build exceeds 89.9 it is set to 89.9 noting that the cross-section’s areas and widths will be close to zero.
6. Fixed bug that didn’t output ZUK0 if Z0 was also specified, and ZUK1 if Z1 was also specified.
Build 2009-07-AA: August 9, 2009 (top)
The July 2009 TUFLOW release is computationally the same as the 2008-08 releases. It has been issued prior to the full 2009 release later this year to provide users with access to completed new features. The manual has not been updated for this release - for details of new features please see July 2009 Release Notes (pdf).
