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 on a HPC cluster

Installing DELFT3D on a HPC cluster

I have been tasked with installing the Delft3D software for use on an academic / commercial use (x86 linux) HPC cluster. Following the instructions from the user who requested this install, I downloaded the following software:

Delft3D-openhydromorpho-4.00.01-02.i386 (GUI, pre and post processing tools plus manuals on LINUX)

However, I am not sure if this is the correct software based on its description - this software seems to assume that the software is to run on one machine where the software is installed (expecting USB dongle with license file). However, the user is expecting to be able to use this software via our batch scheduler so the Delft3D software would need to be available to use on any of the compute nodes across our cluster (which can be achieved). Having installed the software within a file system shared across all compute nodes, the problem I have hit is that the license file supplied does not support such usage - plus the software provided does not contain the required vendor daemon application (dhsdelft).

If there is a different 'version' of the Delft3D software to request / install can someone please advise? Thank you.

sounds like you have just installed the GUI. This is used by your user to setup the files and analyse the outputs.

What you want to install on your cluster is this:

No license file needed and example batch scripts already provided.

Hope this makes it a bit clearer.
