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 attempting to build delft3d4 on CentOS 7 Linux (essentially rhel 7).  In the make ds-install step I get the following.Compiling Data_Type_Command_Line_Interface.F90
src/Data_Type_Command_Line_Interface.F90:11:4: USE IR_Precision                                                                ! Integers an

Fatal Error: Cannot read module file ‘ir_precision.mod’ opened at (1), because it was created by a different version of GNU FortranThe standard GCC on CentOS 7 is 4.8.5.  Since the instructions recommend >= 4.9.1, I have tried 4.9.1, 4.9.3, 5.2.0 and 5.5.0 all with the same result.  I presume I could solve the problem by recompiling ir_precision and producing a new .mod file but I don't find ir_precision as part of the distribution.Am I not looking in the right place for ir_precision.f* ?Can someone who has successfully build delft3d4 on Linux suggest a solution?Thank you.
compile build delft3d4 ir_precision.mod

Shortly after I posted this I got an idea of what I did wrong.  My idea has proven correct.  I will soon delete this post.
