intro story Coast / Estuary

Coast / Estuary

Coastal systems are among the most dynamic physical systems on earth and are subject to a large variety of forces. The morphodynamic changes occurring to coastlines worldwide are of great interest and importance. These changes occur as a result of the erosion of sediments, its subsequent transport as bed load or suspended load, and eventual deposition. 
 
Estuaries are partly enclosed water bodies that have an open connection to the coast. Estuaries generally have one or more branching channels, intertidal mudflats and/or salt marshes. Intertidal areas are of high ecological importance and trap sediments (sands, silts, clays and organic matter).
Within the Delft3D modelling package a large variation of coastal and estuarine physical and chemical processes can be simulated. These include waves, tidal propagation, wind- or wave-induced water level setup, flow induced by salinity or temperature gradients, sand and mud transport, water quality and changing bathymetry (morphology). Delft3D can also be used operationally e.g. storm, surge and algal bloom forecasting.

Error running morphodynamic simulation on Linux

Error running morphodynamic simulation on Linux

Youngling Posts: 4 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?
