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!

Changing matlab codes of QuickAnimate, QuickPlot

Hi,

I would like to know if I can change the Xlim and Ylim from the exported Quick Animate avi that I got. (Refer to attached). I tried to change the M and K range from the QuickPlot matlab GUI, but I would very much prefer to modify the matlab code to change the limits.

Thanks,
Shawn

Hi Shawn,

It's only open the command line in QuickPlot (window>>show command line), and write the limits
>xlim([XXX  XXX])
before animate, as well as in Matlab.

Hi Renan,

I typed this >axis([8 10 -0.1 0.3]) into the command line and pressed enter and a matlab fig came out with these limits. (Figure 1),
next I pressed Quick Animate but the animation axis is not the one that I pre-set. (Figure 2).

Do you know what step(s)I may have missed?

Hi Shawn,

First you need to plot your figure with only one time step (so it's "quick view" button).
After this you open the command line and type the limits.
So, to animate you press "Start Animation" icon in the figure window.

Regards,
Renan

Hi Shawn,
it is great your animation!
Wow, I did not know you can do that kind of simulation with delft3d.

I was wondering, could you tell me, what kind of simulation you did in order to get that animation?
Is a 3d simulation, right?
Are you using the online model wave and flow?
These questions are because I would like to simulate some marine structures and I think that with the answers of my questions, I would have some ideas about how to do my simulations.

Thank you!

Kind regards!

S.
