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.

Possible bug in RGFGRID after entering "Edit Grid" mode

Possible bug in RGFGRID after entering "Edit Grid" mode

Youngling Posts: 1 Join Date: 8/28/18 Recent Posts

Hello!

My name is Anton and I have only recently started using Delft 3D for my work. 

 

In RGFGRID if I have entered the "Edit Grid" mode I am not able to enter either "Edit Spline" or "Edit Polygon", see attachments for a screenshot before entering "Edit Grid" mode and after entering "Edit Grid". 

I am sorry if this has already been answered or if this is the intended behaviour but from chapter 5.2 in the manual it doesn't appear to be intended. I would be very grateful if anyone could help me shed some light on this behaviour. :)

I am running on Windows 10 Pro 64 bit.

 

Maybe there is something obvious that I am missing. :)

 

Yours,

 

Anton
