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!

Error running examples

Hi all,

I compiled Delft3D tag 5740 on Ubuntu 14.04 LTS using gfortran.
Everything seem OK but when I run the examples I always get the following error:

At line 831 of file prterr.f90 (unit = 33, file = 'tri-diag.f34')
Fortran runtime error: Sequential READ or WRITE not allowed after EOF marker, possibly use REWIND or BACKSPACE


However, this errors seems not to affect the result of the simulations.


Besides, when I run specifically example 10 I get:

At line 136 of file rdpart.f90 (unit = 902, file = '')
Fortran runtime error: File already opened in another unit

Delwaq2 did not run correctly.


Thank you very much for any help.
Best regards,
Francesco

I am running into the exact same error when trying example 10. Does anyone have a good idea of how to fix this? I cannot run example 10 successfully (and am having issues with another Del-waq test case I've been trying).

Thank you,

Alejandra Ortiz

Different kinds of difficulties are encountered while working. But every task can be solved if you try to find it. I have also done many difficult things in my life. https://astarios.com/software-security-testing/
