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.

Online-WAVE coupling

I am new to Delft3D and am working my way through the tutorials. I am on the online WAVE coupling tutorial (6.4 in the WAVE user manual) and when I run the model I am getting the following error:

forrtl: The process cannot access the file because it is being used by another process.

forrtl: severe (28): CLOSE error, unit 796, file "Unknown"

I have done a bit of research to see that the error is “forrtl” = fortran run-time library (so it is a fortran error)
“severe (28): CLOSE error” = FOR$IOS_CLOERR. An error condition was detected by the Intel Fortran RTL I/O system during execution of a CLOSE statement.

Some forums suggested it was down to local write permissions but that did not seem to help when I ensured I had full permissions on the drive.

Any help would be vastly appreciated.

UPDATE:

This error was tracked down to Kaspersky Antivirus. The "System Watcher" component was interfering with the communication/ stopping the model.

Disabling the component fixed the issue.

Cheers,
