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 while installing Licence Manager on windows 10 version 2004

I installed the new version of Windows 10 (2004), but now I can't install the license manager. Blue screen appears during the installation, code "PAGE FAULT IN NONPAGE AREA". I think this is happening due to incompatibility with the new version of windows 10. Someone can help me please?

Hello everyone. It's been a while since the original poster started this thread but I can share some insights on how to work around the issue.

I had the exact same problem back in july to august, while trying to install Delft3D 4.04.01 on my new workstation PC (running Windows 10 2004).
It went even worse than mentioned here, as my PC was stuck in a bluescreen bootloop even before logon was possible. Neither uninstalling Delft3D nor any of it's components (in OS recovery mode) could fix the problem. Fortunately I could rollback using a system recovery point created a couple of days before.

My educated guess is that the HASP sentinel dongle driver embedded within DS_Flex went haywire. Note that this was also the case with many other software using HASP sentinel in combination with Windows 10 2004.

So here is the problem: Delft3D 4 Suite 4.04.01 comes bundled with an old version of the licence manager DS_Flex (seemingly from 2018). Simply download the new DS_Flex 7.7.0.0 (June 2020) and everything should work: https://download.deltares.nl/en/lmadmin/

Maybe Deltares can update their bundle so others won't run into the same issue. Especially as Windows 10 2004 has a share (within windows 10) of about 40% nowadays. I hope this will help someone in the future.

Best regards!
