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!

Hi,

Where i can find the source code of calculate surface temperature
tsurf  = r0(nm,k0,ltem)
and temperature in layer?

Thanks.

Hi Mitia,

You are looking for heatu.f90. This code is situated in src/engines_gpl/flow2d3d/packages/kernel/src/compute/
See comments in the file for explanation of the formulas.

Regards,

Dmitry

Hi Dmitriy,

No, i can't find computation of surface temperature in heatu.f90. In this file variable tsurf eq. r0(nm,k0,ltem). So i asked where i can find computation of r0(nm,k0,ltem).

Thanks.

Hi Mitia,

In heatu.f90, heat fluxes at the surface are computed and stored in the arrays sour/sink.

In "src/engines_gpl/flow2d3d/packages/kernel/src/compute/difu.f90" (or the Van Leer variant difuvl.f90), the constituent array at the new time, r1, is computed, based on the constituent array at the previous time, r0, and the sour/sink terms.

Regards,

Adri
