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.

Installing Delft3D in 64 bit OS

Installing Delft3D in 64 bit OS

Good day all,

I installed D3D Flow version in 64 bit OS and started a simple run. Then, the model reads all initial files without any error and goes to the first time step. But it's stuck there and no progress. I suspect, this happens because of the 64 bit OS or some other reason.

Would someone help me to figure this out? I have herewith attached all spec files.

Thanks a lot in advance

PS. it creates a config_flow2d3d.ini file and there is line, wait = yes, may be this cause to stuck the run

Hi Dissa,

You have online visualisation turned on in your mdf file - this will cause it to hang until you start up the RemoteOLV GUI and connect. To get you model running change your mdf file to turn online visualisation off - line 104 in your mdf shoud read:
Online = #N#
I think more recent versions of D3D Flow provide a message saying "waiting for remote OLV" or similar to make it clearer why your model is not running and avoid this confusion.

Thanks a lot Richard, that works fine.
