Line 2:
In this module we will link an existing 2D TUFLOW domain to an existing Flood Modeller 1D model. The 2D TUFLOW domain will represent the floodplain in the study area, and the 1D Flood Modeller model will represent the watercourse and all online structures. <br>
 
1D-2D linked models are able to utilise the individual benefits of 1D and 2D solution schemes. In this example, the 1D Flood Modeller scheme is used to represent the watercourses where the flow is essentially oneuni-directional. A 2D scheme is suited to the representation of floodplains where a more detailedcomplex flow patterns may occur. <br>
<br>
As [[Tutorial_Module01Tutorial_Module01_Archive#Reviewing_Model_Performance | discussed in Module 1 of the TUFLOW Tutorial Model]], the main creekwatercourse channel is not very well represented using the 5m 2D cell size. In parts, the creekwatercourse is only 5-10m wide and the 5m cell size could be considered too coarse to accurately represent the creekwatercourse topography. Refer to the below figure.<br>
[[file:Poor_2d_rep.png|400px]]<br>
Using a cell size that is coarse relative to the width of the creekwatercourse channel may reduce the accuracy of the conveyance in the channel and introduce a source of mass error to the model. There are two options for improving the representation of the creek channel:<br>
* decrease the width of the 2D cells; and/or
* model the channel as a 1D network, dynamically linked to the 2D domain (the floodplain).
In the [[Tutorial_Module01Tutorial_Module01_Archive#Advanced_-_Model_Resolution_.28Optional.29 | optional section of moduleModule 1 of the TUFLOW Tutorial Model]], we looked at reducing the cell size to get a better representation of the channel. In this module we will adopt the second approach of modelling the creek as 1D elements inusing Flood Modeller.<br>
 
<br>▼
TUFLOW may be dynamically linked to 1D networks using the hydrodynamic solutions of ESTRY (TUFLOW 1D), Flood Modeller (previously ISIS), XP-SWMM and 12D Solutions’ Dynamic Drainage.<br>
 
Setting up a 1D/2D model where the 1D channel cuts through the 2D domain is probably the most time-consuming type of a model to setup. However, the reduction in simulation time can be beneficial and make this a good approach. For this module, the complete Flood Modeller 1D model has been provided, soto youallow canfor progressprogressing through the module in a relatively short period of time.<br>
 
=Existing Model Data=
This tutorial builds upon the 2D TUFLOW domain that was constructed as part of [[Tutorial Module01Module01_Archive|Module 1]] and [[Tutorial Module02Module02_Archive|Module 2]] of the TUFLOW Tutorial ModelsModel.<br>
The model developed in these tutorial modules already contains some culverts modelled as 1D elements. The culverts are modelled in ESTRY, TUFLOW's internal 1D engine. One of these culverts will be kept in ESTRY and the other will be changedadded to the Flood Modeller model.<br>
The 2D boundary conditions (upstream inflows and downstream stage-discharge boundary) will be removed from the model. These will instead be represented in Flood Modeller as it is a more typical schematisation for a 1D/2D linked model.<br>
The existing TUFLOW model consists of:

*1D/2D boundary links to connect the 1D ESTRY culverts to the 2D TUFLOW domain.
 
IfFor you need morefurther information on these elements, weplease recommendrefer that you work throughto [[Tutorial Module01Module01_Archive|Module 1]] and [[Tutorial Module02Module02_Archive|Module 2]] of the TUFLOW Tutorial Model.
 
==Flood Modeller==
Line 33 ⟶ 34:
*<b>IEF</b>: A blank folder in which to store Flood Modeller Event Files used to simulate the model.
*<b>RES</b>: A blank folder in which to write the Flood Modeller result files.
For further information on each file type, please refer to the [httphttps://help.floodmodeller.com/floodmodeller/docs Flood Modeller User Manual].<br>
For this tutorial, the floodplain of the study area will be modelled entirely in TUFLOW.
The cross-sections in the Flood Modeller 1D model have been trimmed to the top of bank to ensure there is no double-counting of storage within the floodplain.
Upstream and downstream boundary data is contained separately within the IED files. These will be referenced and linked to the Flood Modeller 1D model via the IEF 1D simulation file.

==TUFLOW Control Files==
==TUFLOW Geometry Control File==
We will first update the TUFLOW Geometry Control (TGC) file.<br> The following changes have been changes made to the geometry:
* We have deactivated the cells along the watercourse which are represented in the 1D Flood Modeller component of the model
The following changes have been changes made to the geometry:
* We have enforced bank elevations along the watercourse.
* We have turned off the cells in the channel (as these are now modelled in Flood Modeller)
* We have added the bank lines as topography amendments.

<li> In a linked Flood Modeller - TUFLOW model, the Start Time, End Time and 2D Timestep are read from the Flood Modeller .ief file. It is best practice to therefore remove these parameters from the tcf. And an exclamation mark in front of each of the below commands.<br>

==TUFLOW HPC==
 
To run the linked TUFLOW-Flood Modeller Pro model using HPC we simply need to add a single line to the Tuflow Control File. The HPC solver will only speed up the 2D calculations within the linked 1D-2D model, it will not speed up the 1D calculations that take place in the Flood Modeller Engine.
The relatively small nature of this specific model means that use of HPC on multiple CPU cores may not lead to significant improvements to model run times. However, should the machine have an NVIDIA GPU card present then it is possible to run the HPC solver on the GPU to significantly improve model runs times. The larger the 2D domain, the more significant the improvements to model run times through the use of the HPC solver.
To utilise the HPC solver:-
 
▲<brol>
<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:
:<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 you have a CUDA enabled NVIDIA GPU device, you can also add the following command to run the HPC solver using GPU hardware:
▲:<font color="blue"><tt>Read GISHardware X1D WLL</tt></font> <font color="red"><tt>== </tt></font> ..\model\gis\1d_x1d_WLL_FMT_M01_001_p.shp GPU <font color="green"><tt>! GIS layer containing WLLs for visualisingRun 1DHPC resultssolver inon 2DGPU</tt></font>
<li> Save the TCF file and run the model.Troubleshooting for GPU Simulation
</ol>
===Troubleshooting for GPU Simulation===
If you receive the following error when trying to run the TUFLOW HPC model using GPU hardware:
<pre>TUFLOW GPU: Interrogating CUDA enabled GPUs …
TUFLOW GPU: Error: Non-CUDA Success Code returned
</pre>
or
<pre>ERROR 2785 - No GPU devices found, enabled or compatible.
</pre>
 
Please try the following steps:
▲<brol>
<li> Check if your GPU card is an NVIDIA GPU card. Currently, TUFLOW does not run on AMD type GPU.
<li> Check if your NVIDIA GPU card is CUDA enabled and whether the latest drivers are installed. Please see <u>[[GPU_Setup | GPU Setup]]</u>.
</ol>
▲<br>
If you experience an issue that is not detailed above please send an email to [mailto:support@tuflow.com support@tuflow.com]<br>
 
=Conclusion=
We introduced the user to the linking of a TUFLOW 2D domain to a 1D Flood Modeller model.<br>
