intro story DELWAQ

DELWAQ

DELWAQ is the engine of the D-Water Quality and D-Ecology programmes of the Delft3D suite. It is based on a rich library from which relevant substances and processes can be selected to quickly put water and sediment quality models together.

The processes library covers many aspects of water quality and ecology, from basic tracers, dissolved oxygen, nutrients, organic matter, inorganic suspended matter, heavy metals, bacteria and organic micro-pollutants, to complex algae and macrophyte dynamics. High performance solvers enable the simulation of long periods, often required to capture the full cycles of the processes being modelled.

The finite volume approach underlying DELWAQ allows it to be coupled to both the structured grid hydrodynamics of the current Delft3D-FLOW engine and the upcoming D-Flow Flexible Mesh engine (1D-2D-3D) of the Delft3D Flexible Mesh Suite (or even other models such as TELEMAC).

'DELWAQ in open source' is our invitation to all leading experts to collaborate in further development and research in the field of water quality, ecology and morphology using Delft3D. Feel free to post your DELWAQ related questions or comments in this dedicated forum space. If you are new to DELWAQ, the tutorial (in the user manual) is a good place to start. A list of DELWAQ related publications is available here.

Error running morphodynamic simulation on Linux

Error running morphodynamic simulation on Linux

Youngling Posts: 3 Join Date: 4/27/18 Recent Posts

We are trying to run a morphodynamic river simulation on a Linux server, however there is a consistent error in the initialization.

*** ERROR Unknown boundary "boundary" in morphology.mor
*** ERROR Flow exited abnormally 

where "boundary" is the name of our upstream boundary and morphology.mor is our morphology characteristics file.

 

We have isolated the problem to the Boundary block in the .mor file, where we specify IBedCond = 3 and ICmpCond = 1.

[Boundary]
   Name             = #boundary#                    Name of boundary as specified in BND file (1 string)
   IBedCond         = 3                             Bedload or bed level boundary condition (1 integer in the range 0 to 5)
   ICmpCond         = 1                             Bed composition boundary condition (1 integer in the range 0 to 3)

Without this block the simulation begins and runs with no problems. However, when the Boundary block is included we get the error message above. The simulation with the Boundary block runs with no problems on a Windows machine. It is only when the Boundary block is included on a Linux machine that it runs into the error.

 

The Delft3D version on our Linux machine is:

URL: https://svn.oss.deltares.nl/repos/delft3d/trunk
Repository Root: https://svn.oss.deltares.nl/repos/delft3d
Repository UUID: 06f92af0-93f6-47d3-9398-6fc6b9b28e5e

And is compiled with IFORT parallel_studio_xe_2017_update3 and using MPICH 3.2.

 

On our Windows machine the version is: https://svn.oss.deltares.nl/repos/delft3d/tags/delft3d4/7545/, and is compiled using Visual Studio 2015 with Intel Visual Fortran Compiler Professional Edition 11.1.

 

Has anyone else encountered this or a similar error? Or does anyone know what a possible solution might be?
