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.

Running flow-3d from GUI -- Linking open source code and GUI

Youngling Posts: 3 Join Date: 7/2/18 Recent Posts

Hi there,

 

I hope this isn't a stupid question. I've tried compiling the open source code many times and after working through a lot of errors I thought I had one compiled that ran the examples correctly. I then downloaded the GUI and created a grid. When I tried running this scenario with the flow module, it gave me errors saying it couldn't find the flow executable nor some databases. 

 

I never linked the open source code to the GUI in anyway, they're just in the same folder. Is there a way to tell the GUI where the open source code is saved? Should I have copied the binaries to the GUI folders? 

 

Here is the error: 

   Starting Delft3D-FLOW computation ...
d_hydro ABORT: Cannot load component library "flow2d3d.dll". Return code: 126

child process exited abnormally

 

Thank you for any help,

Alex Miller

Hi Alex,

You have to copy the the binaries to the GUI folder. See the source code page, section 5.2, for instructions.

Adri

Thank you! I forgot to do that. 

 

However, I still am getting the above message. Maybe I did not compile the open source code correctly after all? I am recompiling another attempt now and keeping an eye on my memory during. I received some errors during my last compile, but one of the example scripts ran so I left it be. 

 

Thanks again,

Alex

I ended up compiling the open source code correctly and running the model. I think increasing my computer's memory helped. 

However, one project did not compile correctly, and I left it without compiling. It was "vs" under tools_gpl>vs>vs (see attachment). 

Do you think this will be a problem? 

Thanks,

Alex

Hi Alex,

 

Neglecting project "vs" is not a problem. It will be removed from the build projects in the next tagged version.
