intro story D-Flow FM

 

D-Flow Flexible Mesh

D-Flow Flexible Mesh (D-Flow FM) is the new software engine for hydrodynamical simulations on unstructured grids in 1D-2D-3D. Together with the familiar curvilinear meshes from Delft3D 4, the unstructured grid can consist of triangles, pentagons (etc.) and 1D channel networks, all in one single mesh. It combines proven technology from the hydrodynamic engines of Delft3D 4 and SOBEK 2 and adds flexible administration, resulting in:

  • Easier 1D-2D-3D model coupling, intuitive setup of boundary conditions and meteorological forcings (amongst others).
  • More flexible 2D gridding in delta regions, river junctions, harbours, intertidal flats and more.
  • High performance by smart use of multicore architectures, and grid computing clusters.
An overview of the current developments can be found here.
 
The D-Flow FM - team would be delighted if you would participate in discussions on the generation of meshes, the specification of boundary conditions, the running of computations, and all kinds of other relevant topics. Feel free to share your smart questions and/or brilliant solutions!

Tutorial for pre-compiled version

Youngling Posts: 1 Join Date: 2/8/12 Recent Posts
Hi,

I have just received the pre-compiled version and wanted to go through the users-manual example.
Unfortunately I have not received the tutorial directory.

Is there a chance to receive those examples?

Thank you in advance

Hi Eva,
my problem is exactly same.Have u solved the matter anyway regarding installing tutorial ? If so,then I would appreciate if you also help me in finding the same and running it in delft3d.

Hey Eva

Sorry for the bug, but do you know what is the difference between this pre compiled version and the one we should compile?

Thank you

Hi Marcelo,

The pre-compiled version is based on the same source code, so there is no difference in functionality.
If you check the version number of the pre-compiled version then you can download the associated source code from the repository (generally one of the tagged versions).

So, the differences are:
  • We compiled the FLOW, WAVE, etc engines for you.
  • We verified and tested that those executables work properly together and give results consistent with or improved compared to previous versions.
  • Include some hours of support depending on the extend of the Service Package.

Hi Bert I am back trying to use this wonderful software.

So I have no need for further actions, I can use the software without any extra compilation? I ask again because I read in another post that I have to compile something else which is not clear to me.

Thank you

Marcelo

Hi, Marcelo,

If you logged in the oss website, go to the download page, you will see the

TEMPORARY EXTRA SERVICE

at the top of the page. There is a link of setup of the GUI, including the tutorial files as well. The description of the tutorials is in the manual as Bert stated above.


I don't understand what you mean the extra compilation.

Thank you Qinghua,
I asked for that extra compilation because someone else wrote me this to the same question "open source Delft3D instaler includes pre-compiled binaries of the user interface (GUI), pre and postprocessing tools, but it requires you to compile the Delft3D-FLOW and WAVE executables yourself. There are webinars on how to do it"

Therefore I am still confused if I can go ahead and just use without changes the version in TEMPORARY EXTRA SERVICE or I need to do something else.


Best!

Moreover when I ran this precompiled version following chapter 5 from the Flow guide. I get the message in the figure attached.

Thank you

Marcelo

Hi Marcelo,

So there are 2 different things. GUI (the installation packages, including tutorials, but not include the deltares_hydro.exe), the executables(deltares_hydro.exe) compiled from the source code.

These 2 are free. But you have to connect them by yourself. You have to compile the source code to get the executables and put them in the right place.

I hope it is clear now.

Greetings,

Qinghua

RE: Tutorial for pre-compiled version

I have the tutorial files, but don't see how to run the tutorial.

How long does one usually have to wait for a reply? Is this an active user's group?

Hi Jon,

We try to keep the forum alive, but we have to balance resources. Please understand that questions via Delft3D support from clients with Service Packages have priority as well as most of the other work that brings in money that keeps software development going. However, we try to avoid that questions remain unanswered for more than 2 weeks, but it's easy to miss follow-up questions in existing threads.

It's not clear to me what you mean exactly by your question "I have the tutorial files, but don't see how to run the tutorial." Most of the Delft3D manuals contain a Tutorial chapter; these chapters require some basic data files to get started and those files are included in the tutorial files installation. So, I assume that the answer to "how to run the tutorial" is: read the Tutorial chapter in the manual of the Delft3D program that you want to learn.

Best regards,

Bert

Hi,

Bert: Could you please tell us where we can get the tutorial files though?

Thanks,
Rohit.
