intro story DELWAQ

DELWAQ

DELWAQ is the engine of the D-Water Quality and D-Ecology programmes of the Delft3D suite. It is based on a rich library from which relevant substances and processes can be selected to quickly put water and sediment quality models together.

The processes library covers many aspects of water quality and ecology, from basic tracers, dissolved oxygen, nutrients, organic matter, inorganic suspended matter, heavy metals, bacteria and organic micro-pollutants, to complex algae and macrophyte dynamics. High performance solvers enable the simulation of long periods, often required to capture the full cycles of the processes being modelled.

The finite volume approach underlying DELWAQ allows it to be coupled to both the structured grid hydrodynamics of the current Delft3D-FLOW engine and the upcoming D-Flow Flexible Mesh engine (1D-2D-3D) of the Delft3D Flexible Mesh Suite (or even other models such as TELEMAC).

'DELWAQ in open source' is our invitation to all leading experts to collaborate in further development and research in the field of water quality, ecology and morphology using Delft3D. Feel free to post your DELWAQ related questions or comments in this dedicated forum space. If you are new to DELWAQ, the tutorial (in the user manual) is a good place to start. A list of DELWAQ related publications is available here.

Problem nesting grids on a tidal model

Youngling Posts: 5 Join Date: 2/21/14 Recent Posts
Hello all,

I am trying to set up a tidal model with a two-level nesting on Delft Dashboard using the tutorial provided by Deltares. From the tutorial, I'm expected to create a coarse grid for the California area and a finer grid for the San Diego bay and merge both grids using the nesting tool.

The problem is when I get to the part where I need to select the Admin File under the Nesting-2 tab, the Administration File is missing in the folder. I believe I have followed the tutorial correctly although some instructions are not clear.

Here is the link to the tutorial:
http://publicwiki.deltares.nl/display/DDB/Set+up+a+Tidal+Model+with+a+Two-level+Nesting

Any help is appreciated

Hi Augusto,
I expect you ran the first step of the nesting (in the first tab). The nesting administration file that was generated during that step should be present in the directory in which you were working. Can you find it there?
Cheers,

Hi Maarten,

Yes, I did run the first step of the nesting but no administration file was generated in the directory though. Any other idea what the problem might be please?

Thanks in advance,
Augusto

Hi Augusto,

I am having the same problem. Were you able to resolve the issue?

Thanks!

Hi

I am having a similar problem where I cannot generate the nesting.adm file due to an error in matlab.

Reference to non-existent field 'dataDir'.

Error in ddb_NestingToolbox_Delft3DFLOW_nest1>nestHD1 (line 90)
exedir=handles.toolbox.nesting.delft3dflow.dataDir;

Error in ddb_NestingToolbox_Delft3DFLOW_nest1 (line 74)
nestHD1;

Error in gui_addElements>finishCallback (line 1249)
feval(element(i).element.callback,element(i).element.option1,element(i).element.option2);

Error in gui_addElements>pushbutton_Callback (line 1166)
finishCallback(element,i);

Error while evaluating uicontrol Callback


I have a feeling I've missed a basic step somewhere but I just can't find it.

Many thanks

Hello! I usually work with nesting and I didn't have any problems.

In this link https://publicwiki.deltares.nl/display/DDB/Nesting there is a more detailed explanation than in the video. You can check also in Flow manual,
in appendix F Delft3D-NESTHD there are some restrictions that it's importantant to take into account.

I hope this help you!
