=Run the Simulation=
Using your preferred method for starting TUFLOW, run '''M02_5m_001.tcf'''. Please refer to <u>[[Tutorial_Module01_Archive#Running_TUFLOWRun_Simulation | Module 1]]</u> for a detailed description of the various methods for running a TUFLOW simulation. Example batch files have been included in the complete model download for reference. <br>

=Review the Results=
==2D Results==
The 2D model results can be viewed using the same methods described in <u>[[Tutorial_Module01_Archive#Viewing_the_ResultsViewing_Results | Module 1]]</u>. You should notice the flow now passes under the road embankments through the 1D culverts. However, at the peak of the flood event the flow in the creek exceeds the capacity of the culverts and two of the three road embankments are over-topped.
 
==1D Results==
Line 145:
The model was simulated and the 1D results reviewed using a combination of GIS software and Excel.<br>
In the next module of the tutorial we will be modifying the 2D topography to incorporate surveyed breaklines. This can be found on the [[Tutorial_Module03_Archive | Module 3]] page.<br>
In Module 4 we will model the creek as 1D channels, linked to the 2D model. This module has not yet been updated to the online wiki format, the previous version (MapInfo only) can be found [http://www.tuflow.com/Tutorial%20Model.aspx?Model2007 on the TUFLOW website].
 
=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.

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). We will review relevant log messages and results.

==Results==
Using the methods described in the <u>[[Tutorial_Module02_Archive#Viewing_the_ResultsReview_the_Results | ViewingReview the Results]]</u> section above:
* Check the simulation logs in the DOSconsole window, .tlf and .hpc.tlf log files. What proportion of the compute effort was spent on the 0D (initialisation, input / output communication between CPU and GPU, etc.), 1D modelling (CPU) and the 2D modelling (GPU)? Example compute percentage output is highlight below from the DOSconsole window. <br>

* View the results in your preferred package. How do they compare to the TUFLOW Classic results?
