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.

Optimal machine build for D3D?

Padawan Posts: 70 Join Date: 6/25/12 Recent Posts
Hi All,

I'm thinking to buy a new computer for the primary purpose of running D3D models. Of course, I enjoy heavy matlab computing as well.. and want graphics capabilities to make fast, intricate plots (and dual monitors).

I'm curious if any one has suggestions about recent builds or hardware specifications particularly well-suited for running fast, stable D3D simulations.
Mainly, I use D3D for morphological modeling (FLOW-WAVE coupling with sediment updating).

Thanks in advance for your advice,
Shawn

Hi Shawn,

Some tips:

Hardware:
Use Intel processors (in combination with the Intel compiler).
A lot of cores is only interesting when you can run parallel. If you mainly do combined FLOW - WAVE calculations, SWAN will use all cores but FLOW won't. Using DomainDecomposition will enable FLOW to use more than one core. Of course you can always do separate calculations at the same time.

Software:
Linux is faster than Windows.
Use the Intel compiler (in combination with Intel processors).

Regards,

Adri

Thank you for the tips Adri. I will keep that in mind.

Any other tips? E.g. Intel i7 vs Xeon? Minimum graphics card, e.g. Is NVIDIA GeForce GT640 enough, or should I shoot more for NVIDIA Quadro 2000 bottom end?

Hi Shawn,

I did not do any detailed performance tests, but looking at some tests in another project, i7 seems to be faster than Xeon. Graphics is not a bottle neck.

<p>Hi All</p>

<p>&nbsp;</p>

<p>8 years have passed since the publication of this post.</p>

<p>If I usually run wave-flow coupled 2D and 3D models (wind, waves, tide, discharge, sediment).&nbsp;Which computer characteristics can improve the computing time of MPI Delft3D v4 or&nbsp;Flexible Mesh&nbsp;models?</p>

<p>I&#39;m about to buy a high performance computer mainly for usage of&nbsp;Delft3D and FM software.</p>

<p>Any new tip or suggestion will be highly appreciated</p>

<p>Kindly regards,</p>

<p>Teresa</p>
