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.

SWAN output files

Hello all,


Does anyone know how to have Delft3D retain the output files from SWAN after the simulation has finished? I'm mostly interested in the PRINT file generated by SWAN. I can see this file while the simulation is running, but after the simulation is done, the file is gone and there is no *.prt file. 


I ask because I would like to see the accuracy in the simulation and whether or not the solution converges (accuracy in >98% of the domain). This leads to a second question:


Does anyone know if there would be some sort of output from Delft3D if the model does not converge on any of the timesteps? Or does it just output the results regardless of the accuracy being obtained?


Thanks to anyone in advance emoticon


Best,
Sam
