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!

delwaq1.f: Fortran runtime error on line 548 (examples 06 and 10)

Hi,
I've complied "successfully" delft3d on xenial 64bit. II got errors on delwaq examples. Others work fine.

The error on 06_delwaq and 10_delwaq-part-tracer is:

At line 548 of file delwaq1.f
Fortran runtime error: Inquire statement identifies an internal file

Any help will be appreciated.

RIccardo

**update**
About 06_delwaq I commented lines 548 549 551 in delwaq1.f:

!
! Close all open LUN files
!
do i = 1, nlun
!!!! inquire (unit=lun(i), opened=unitop)
!!!! if (unitop) then
close (unit = lun(i))
!!!! endif
end do

About 10_delwaq-part-tracer, now I got this error:

At line 136 of file rdpart.f90 (unit = 902)
Fortran runtime error: File already opened in another unit

I get the same error on Example 10. Everything else runs fine. I compiled tag 7545 on Ubuntu 16.04 64bit (which was an ordeal in itself).

I get the same error too.
Please any advice to solve it, will be very helpful.

Hi All,

Sorry for the late reply to this, it in not on the standard Delwaq forum that I follow.

Both errors stem from the fact that apparently the compiler you are using is a bit more stringent on opening files that the ones we use. The first issue with delwaq1/ 06_delwaq was resolved in revision 7205. Apparently you are not allowed to inquire internal files. I added a catch for any error situations.

I'll have to look into the rdpart issue later.

As for the issue with example 10, I've committed a fix to revision 8067 for the rdpart code. However, the current trunk might not be stable. If you want to use the WAQ_PART combo, you can apply the fix to the latest tagged version.

Thank you Michelle,


However I still have doubts about the implementation of this new revisions.
Do I have to re-install Delft3D? If I have to, Where are the new folders? (https://svn.oss.deltares.nl/repos/delft3d/trunk/src/)?
If I don't need to re-install, Do I have to check any files and download them to my folders? Which ones of them?


Thank you,

Mariana.



EDIT...

I succesfully compiled Delft (again).
I used Revision 8114. Tag 7545 https://svn.oss.deltares.nl/repos/delft3d/tags/7545/. Although, I had to correct the path of mpi installation at the build.sh file (I installed Delft in Linux).

Now it runs del_waq properly.


Best regards.

Hi,

The fix is in only one file: https://svn.oss.deltares.nl/repos/delft3d/trunk/src/engines_gpl/part/packages/io_f/src/rdpart.f90. We are still reorganizing the way the executables are put into a tree, and the menu needs to be adapted for that. To use the old file structure, but include the fix for the issue with example 10, download the latest tagged version of the code:

https://svn.oss.deltares.nl/repos/delft3d/tags/7545

Patch (overwrite) the file src/engines_gpl/part/packages/io_f/src/rdpart.f90 with the latest version from the trunk here (log into the website with your svn credentials):

https://svn.oss.deltares.nl/repos/delft3d/trunk/src/engines_gpl/part/packages/io_f/src/rdpart.f90

And then build the code again.

Michelle
