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!

    the number of the layers is 100 at most. when i make the number of the layers exceed 100, such as 150, it will apears error, so how can i solve it, the following is the error: ******************************************************************************** *** *** Deltares, FLOW2D3D Version 6.02.13.62541M, Nov 6 2018, 12:53:18 *** built from : https://svn.oss.deltares.nl/repos/delft3d/branches/releases/7545 *** *** runid : JLR_YZR_steady *** date,time : 2019-08-31, 23:08:53 *** ******************************************************************************** *** ERROR Number of layers too large.

  • Teodósio Nzualo

    Dear, My name is Teodósio Nzualo and i'm a pos-doc research in Federal University of Rio de Janeiro. I user the Delft3D since 2010 in free version. In March 1, 2016 i received from Deltares the last License which i'm using. However in March 18, my QUICKPLOT left to work. The mensage that i received is "Error in mclFreeStackTrace". What could it be? Is it a error of compiler R2013? and how to resolve it? I'm using the Delft3D in version 4.01.00.02. 1 - MCR_R2013b_win32_installer 2 - vcredist_x86 (2010 SP1) 3 - delft3d_tutorial_x86 4 - delft3d_binaries_x86 5 - DS_Flex Specifications of my PC Processor: Intel(R)Core(TM) i7 CPU 2.93 GHz Memory RAM: 6.00 GB System type: 64-bit Operating System, x64-based processor And i'm using a Windows 10 Thanks for your attention.

  • Version and Compiling

    I am trying to use Delft3d version 4.01.01.rc.03. I want to know, for this version of Delft3d, which flow tag should I use? Similarly, if I want to use Delft3d version 4.02.02, which flow tag version should I use. And what is the flow tag version that i should use for Delft3d version 4.00.02? I am trying to compile the source code since last week but there is always some errors and problems. I am using Microsoft visual studio 2010 and intel parallel studio XE 2015. Is there any way i can run Delft3d for simulation without compiling the source code? I would be very much thankful for your support.
