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.

Compilation Error: Skipped Build:Project: flow2d3d_openda

Well another compilation problem...

I used first MVS 2010 with IFORT 12 and now MVS2017 with IFORT18.

The Problem is that Im building an everything seems ok until I get an output as seen in the screenshot at the end...

then no error appears but instead the computer keeps calculating an uses more and more memory... it stays in a loop and the threads running just grow and grow it seems like...

any ideas why?

Thank you!

Hi Samuel,

I ran into similar problems on a PC with only 4 GB of RAM memory. Can you check the memory usage in the Windows Task Manager while compiling? Do you hit memory boundaries? It might be enough to switch to compiling one project at the time: in VisualStudio: menu -> Tools -> Options -> Projects and Solutions -> Build and Run -> maximum number of parallel project builds

Regards,

Adri

Hi,

We've had the same problem with VS2015 and IFORT18 on a couple of different machines. VS won't let you exit as the build is still running but there is no way to cancel out of the build. Only way to exit is to reboot!

I'll try compiling one project at a time as you suggest Adri.

Cheers,

Richard

We've tried turning off parallel builds and still get the same problem. How did you get on Samuel?

 

Any other suggestions Adri?

 

Thanks, Richard

Hi Richard,

Check in the Task Manager that you really hit the memory boundary. If you do, the easiest solution is to extend the memory on your machine.

Adri
