=Introduction=
In this module we add some breaklines to the model to ensure that the 5m cell size model correctly represents the key hydraulic controls. We will add break-lines to represent the following features:<br>
* Road crests
* Creek centre line (thalweg)
The only new GIS layer that is introduced is the 2d_zshape (2d Z Shape), it- isrefer recommended thatto the user reads section 4<u>[https://docs.4tuflow.9com/classic-hpc/manual/latest/ ofTUFLOW theManual]</u> 2010for TUFLOWmore manualinformation. The 2d_zsh layer is commonly used, and will be also used in later modules.<br>
'''Note:''' As per module 2, instructions are given for the following four GIS platforms:<br>
* MapInfo

=Run the Simulation=
Using your preferred method for starting TUFLOW, run the recently created '''M03_5m_001.tcf'''. Please refer to <u>[[Tutorial_Module01_Archive#Running_TUFLOWRun_Simulation | moduleModule 1]]</u> for a detailed description of the various methods for running a TUFLOW simulation.<br>
If the model fails to start correctly please refer to the <u>[[Tutorial_Module03_Archive#Troubleshooting |troubleshooting section]]</u> at the end of this page.<br>

=Troubleshooting=
This section contains links to some possible issue that may occur when progressing through the second tutorial module. If you experience an issue that is not detailed please detail the issue on the <u>[[Talk%3ATutorial_Module01_Archive | discussion page.]]</u><br>
 
If you are unsure of why the model has failed to start, check the TUFLOW Log File (this is in the '''TUFLOW\runs\log\''' folder and has the name '''M02_5m_001.tlf'''. This can be opened in a text editor, the error is generally at the end of the file, however you can search for "Error" if you can not see the error.

= Advanced - HPC Solver (Optional) =
In this optional section we will run the model using the TUFLOW HPC (Heavily Parallelised Compute) solver.

TUFLOW HPC can run between 10 and 100 times faster than TUFLOW Classic using NVidia Graphics Processing Units (GPU)(depending on the model configuration and hardware performance). TUFLOW HPC exhibits unconditional stability. As such, It will automatically select a timestep to maintain simulation stability. This tutorial discusses this feature.

'''MapInfo Users'''<br>
* Import the '''2d_iwl_empty.mif''' file from the "mi\empty" folder and save as '''mi\2d_iwl_M03_004.tab'''.
* Draw a polygon around the pond in the center of the active model area. Set the "IWL" attribute to 75m. Save and export the file as a MIF/MID file.<br>

* Add the following command to the '''M03_5m_004.tcf''' file:<br>
Line 227 ⟶ 228:
* Review simulation results thoroughly; and
* Review the model timestep information as a method to identify possible locations containing data input errors.
