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.

@ echo off
rem
rem This script runs Delft3D-FLOW parallel
rem

set argfile=config_flow2d3d.ini

rem Set the directory containing ALL exes/dlls here (mpiexec.exe, delftflow.exe, flow2d3d.dll, mpich-dlls, DelftOnline dlls etc.)

set exedir=c:\Delft3D_OS\w32\flow\bin\

set PATH=%exedir%;%PATH%

rem Run
rem start computation on local cores (2 for dual core; 4 for quad core etc.):
mpiexec -n 2 -localonly deltares_hydro.exe %argfile%

Hey dude,

Thanks for posting this up.

Just a quick question though. I am a noobie in command prompt and I wonder how do I use this script?

Anyone mind giving me a guide?

Much thanks for all the help guys. emoticon

Hi Jack,

When you download a recent version of the source code, example testcases will be included, containing batch scripts (*.bat for Windows, *.sh for Linux). Check that the paths in the script point to exisiting directories, containing the executables. Then execute the script by double-clicking in a browser.

Regards,

Adri
