=GIS and Model Inputs=
The steps necessaryrequired to modify each of the GIS inputs are demonstrated in QGIS using SHP and GPKG formats. IfInstructions youfor would like to view instructions forcompleting the tutorialmodule in ArcGIS or MapInfo theseare can be foundavailable on the archive page for [[Flood_Modeller_Tutorial_Module01_Archive | Tutorial Module 01]].
 
===Define the External 1D Networks===
This part of the module creates the GIS layers that specify the location of the Flood Modeller nodes that are to be connected to the 2D domain.
 
Follow the instructions below for yourthe preferred GIS format.

Line 38:
This part of the module creates the 1D/2D boundaries to link the Flood Modeller 1D component to the TUFLOW 2D domain.
 
Follow the instructions below for yourthe preferred GIS format.

<li> Save the TUFLOW runfile (<b>FMT_M01_001.tcf</b>) as <b>FMT_M01_002.tcf</b>.</li>
<li> Add the following command to the TCF file:<br><font color="blue"><tt>Solution Scheme </tt></font> <font color="red"><tt>== </tt></font>HPC <font color="green"><tt>! Use HPC solver to run the simulation</tt></font>
<li> If a CUDA enabled NVIDIA GPU device is available, the following command may be added to run the HPC solver using GPU hardware.:<br><font color="blue"><tt>Solution SchemeHardware </tt></font> <font color="red"><tt>== </tt></font>HPCGPU <font color="green"><tt>!

<li> If you have a CUDA enabled NVIDIA GPU device, you can also add the following command to run the HPC solver using GPU hardware:<br>
<font color="blue"><tt> Hardware </tt></font> <font color="red"><tt>== </tt></font>GPU <font color="green"><tt>! Run HPC solver on GPU</tt></font>
<li> Save the TCF file and run the model.
</ol>
=== Troubleshooting for GPU Simulation ===
If you receive the following error whenis tryingencountered towhen runrunning the TUFLOW HPC model using GPU hardware: :
<pre>TUFLOW GPU: Interrogating CUDA enabled GPUs …
TUFLOW GPU: Error: Non-CUDA Success Code returned
Line 182 ⟶ 180:
Please try the following steps:
<ol>
<li> Check if yourthe GPU card is an NVIDIA GPU card. Currently, TUFLOW does not run on AMD type GPU.
<li> Check if yourthe NVIDIA GPU card is CUDA enabled and whether the latest drivers are installed (see <u>[[GPU_Setup |GPU Setup)]]</u>.
</ol>If you experience an issue that is not detaileddescribed above pleaseis sendencountered, an email should be sent to [mailto:support@tuflow.com support@tuflow.com].<br>
