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.

Domain Decomposition,wrong coupling point

Hello,
I was wondering  if anyone can help me regarding my project. I'm working on delft3D software for my thesis. I have some problem with running domain decomposition models in my model.

1) Error during initialization of subdomains: check tri-diag files.
OR
2) "riv_pesikhan": Wrong coupling point at (366, 5) Kcs=1 KcsInside=0


I do not know what my problem is.
Thank you in advance for your time and consideration.
Sincerely,
Farshad

Not sure if the thesis is done already but I tried to do a quick check the data in your mdf is not complete in the rar file.
