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!

Delft3D & Centos 6

I would appreciate some help with a Delft3D CentOS 6.2 installation problem.

I have downloaded the Delft3D files, installed the Matlab compiler runtime and the dongle driver but haven't been able to complete the Delft3D installation, see below for the response to the rpm command:

[root@civ76 Delft3D_4.00]# rpm -ivh Delft3D-openhydromorpho-4.00.01-02.i386.rpm
error: Failed dependencies:
libtcl8.4.so is needed by Delft3D-openhydromorpho-4.00.01-02.i386

It seems that libtcl8.4.so is required but I have not been able to find a location where this package can be downloaded from.

The closest that I have found is here, http://pkgs.org/centos-5-rhel-5/centos-rhel-i386/tcl-8.4.13-4.el5.i386.rpm.html , but this is for Centos 5.

Please suggest where libtcl8.4.so can be downloaded from or an alternative way of overcoming this problem.

Best regards,

I have posted a question in relation to this problem on the CentOS forum, see https://www.centos.org/modules/newbb/viewtopic.php?topic_id=38502&forum=56&post_id=167902#forumpost167902.

The response was that, based on the error messages, the precompiled version of Delft3D that I am trying to install is intended for CentOS 5 rather than CentOS 6 and that rebuilding on CentOS 6 is required for it to run. However for this to be possible the source code version of Delft3D-openhydromorpho-4.00.01-02.i386.rpm is required.

Is this available or should I start again with a version that has not been precompiled?

Best regards,

As a source code version of Delft3D-openhydromorpho-4.00.01-02.i386.rpm does not appear to be available I have downloaded an uncompiled version and succeeded in compiling it without generating any error messages; the test calculations also seem to work.

The question now is where can I get the Linux version of the GUI seperately rather than as part of the whole Delft3D package
.
Any comments or suggestions appreciated.

It seems to me that an impasse has been reached; initially when Ubuntu was used it eventually transpired that Red Hat/CentOS was the preferred version of Linux and that Ubuntu was not really supported at all, see link below

http://oss.deltares.nl/web/opendelft3d/od3dforums/-/message_boards/view_message/98602/maximized#_19_message_156596

Following from this Ubuntu was replaced with CentOS 6 but it then transpired that CentOS 5 was required for compatibility with Delft3D-openhydromorpho-4.00.01-02.i386.rpm as it requires libtcl8.4.so which is only available for CentOS 5 , see link below

http://oss.deltares.nl/web/opendelft3d/od3dforums/-/message_boards/view_message/169073/maximized#_19_message_169073

The other layer of difficulty, as can be seen from this thread, is that the only responses to my recent posts have been from myself, which I have to admit are not much help.

Overall then the experience has been far from satisfactory.

I agree, about the response. I have some issues with newer versions of Ubuntu and Suse which have damaged paths in d3d_menu. I got no response whatsoever.
The annoying part is that I actually could help resolving the problem (mine).

Your problem is easier to solve as you can probably create a symbolic link from the newer tcl library to the older name. It may work. You need root access to do that.
