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!

Between ifort - gfortran - mpif90 for DFM compilation in LINUX

First of all I would like to greet : "Happy New Year 2014" , wish you success in this year.

In the tutorial page (http://publicwiki.deltares.nl/display/DFLOWFM/Building+on+Linux), it was stated that we should use similar compiler during the installation.

If I want to compile DFM for MPI, shall i use mpif90 since the beginning to compile NETCDF, PETSC, METIS, etc. ? (because I will compile DFM using mpif90)

Thanks

In my opinion all those compiler have the the same function. However, during the compiling process, we should be consistent and follow the procedure stated in the tutorial.

However, if you use ifort, when you move the installed system to another computer, you have to adjust and set the ifort license in the new computer.

Good day emoticon :smile:

Just for completeness:
What is beyond the scope of the D-Flow FM build instructions:
* compiler license issues
* compiler paths/settings (We mention the well-known ifortvars.sh as an example only.
* mpi flavours (although we do share some experience with versions)

We do strive to specify library versions, so what is in the scope:
* third-party libraries, such as NetCDF and PETSc.
* build steps/order

Moving installations to another machine is possible, but not recommended nor strongly supported, because of all the dependent libraries: the machine on which you built the software may have other system or compiler libraries than the target system that you're copying the software to.
