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!

I am getting this error and can't figure it out. I have seem similar posts that say to set

export NETCDFROOT=/usr/local
export PKG_CONFIG_PATH=/$NETCDFROOT/lib/pkgconfig:$PKG_CONFIG_PATH

Which I have done and pointed it to the right path.

I am using the build.sh with the following command line.

sudo ./build.sh -64bit -gnu -configure "-- prefix=/usr/local FC=mpif90 F90=mpif90 CC=mpicc F77=mpif77 FFFLAGS=-fno-range-check"

mpif90 --version
GNU Fortran (Ubuntu 4.9.2-0ubuntu1~14.04) 4.9.2

Any assistance would be greatly appreciated.

I'm also having this problem. I have the gfortran version 4.8.4. Have you solved this issue?

*EDIT: I solved this issue by adding the suggested flag to the command. This results in

CFLAGS='-O2' CXXFLAGS='-O2' FFLAGS='-O2' FCFLAGS='-O2 -fno-range-check' ./configure --prefix=`pwd`

with the "-fno-range-check" added.*

Best regards,
