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.

Clean up of model failed

Hi,

I had a flow model running no problem (in both 2D and 3D), I then made another model exactly the same but with a new (much finer mesh) grid and now the model still runs but fails just at the end when it gets to the "cleaning" stage.

The error is gives me is "Couldn't open grid nc file: C:/......etc.etc._map.nc because of err nr : - 2002" and "Clean up of Flow model has failed"

If I look for results after this, there isn't any time series to query or anything in the model itself but it is still writing the his, map and restart files as outputs which look normal however when I look into those files using Quickplot then the results are clearly not right - somethings gone wrong.

What can I do to fix this cleaning error?
