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.

Online Coupling FLOW WAVE -working but no results!

Youngling Posts: 1 Join Date: 1/14/17 Recent Posts
Hey,

I am trying to model a hydro-morphodynamic Situation by coupling Delft3D FLOW and WAVE (for now without sediment).
Seperated from each other they work perfectly, so it's not about the boundaries. After coupling they work for 2 of my 25 simulation days perfectly and after the results of SWAN stay 0.

Here you can see my results so far:

And the iteration never satisfies the accuracy. It seems that it stops after the first iteration step and repeats always the same iteration.
What can I do???

Please help me!
Kind regards, Anna
