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. 
On this discussion page you can post questions, research discussions or just share your experience about modelling coastal and/or estuarine systems with Delft3D FM.

MPI mode FLOW and WAVE model

MPI mode FLOW and WAVE model

Hi all,

I could run Delft3D FLOW model with MPI mode. However, I could not run FLOW model with (offline-SWAN) WAVE model results. That is because the com-file from the WAVE model could not be recognized, is it right? In other word, it is impossible to run FLOW and WAVE model parallelly instead of FLOW model only.

Hi To Dang,

Yes. You cannot run flow online with wave in parallel.

We are still busy with it.

Does this issue resolved??

and one more thing i wanted to know.

when flow is run in parallel mode, I've seen from quick plot that the partition consists of parallel bands divided on y axis mostly.
is there any option for checkered squares or some other partition technique??
if its so please let me know.

Thanks in advance!

Pls refer to: do I run a calculation in parallel?

The progress about parallel computation is shown in the

The partition of the domain is carried out automatically by hardcoded. So you cannot choose blocks instead of bands(strips) at present stage.

Hope this will help a bit!
