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!

file 'norm_end' expected to signal a correct swan calculation

file 'norm_end' expected to signal a correct swan calculation

While making a wave alone delft3d run in 64 bit windows platform, i encountered an error. The error showed in command running dialogue box is " file 'norm_end' expected to signal a correct swan calculation", while in the err file, the error reported is "Terminating error: Allocation problem: array AC2 and return code is 41".

I could find many suggestions on how to make the model run perfectly or to fix probable mistakes I could've done, like the stack overflow error.

However I'm confused very much with it, because with all the same files (nothing changed), I was able to run the model in a different computer(PC) with almost same configuration as the previous one. (kindly note that the model was perfectly run in the new PC, hence proving no stack overflow error)

I'd like to know what exactly could be the reason for this. Is this some kind of a bug or is it my PC configuration that cause the issue, or something else?

(Note that this system, which showed error was previously used to successfully make similar wave standalone runs)
