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!

NEFIS files are bad, warnings in compilation

NEFIS files are bad, warnings in compilation

Dear all, 
A few days ago I posted a request for help because I was not getting GPP to work. After checking and checking I realized the problem is not GPP, but something related to the flow simulation. I can generate mdf files and process the simulation without giving errors. I believe the problem is in the generation of the map, drogue, and history files. Therefore, the problem is the generation of the NEFIS files.
Then I compiled everything again, and I get 0 errors, but 130 warnings. Several are of the type MSBuild. I read I have to disable this in VS 2015. But I cannot find the way to do that.  
Question 1. Am I right about this diagnostics?
Question 2. How can I disable or uninstall MSBuild from VS 2015?
Question 3. Any other suggestions?
Thanks for any help

Hi Jorge,
Have you tried to run examples from the 'examples' folder after having compiled D3D executables? If they run smoothly, try to use QUICKPLOT instead of GPP to inspect the results. If needed, see Quickplot user manual. In case you have problems with generating NEFIS files, you can store simulation results in the NetCDF-files. Have a look at the section A.1.4 of FLOW user manual for the detailes.
Regards,
Dmitry

Thank you a lot Dmitry. I skept the examples, my bad. I tried a couple of them and they worked fine. I opened the history files with quickplot and everything shows right. So, I don't know, a problem with GPP I believe. Important thing is that the model is working. Cheers
