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.

SWAN output files

Hello all,

Does anyone know how to have Delft3D retain the output files from SWAN after the simulation has finished? I'm mostly interested in the PRINT file generated by SWAN. I can see this file while the simulation is running, but after the simulation is done, the file is gone and there is no *.prt file. 

I ask because I would like to see the accuracy in the simulation and whether or not the solution converges (accuracy in >98% of the domain). This leads to a second question:

Does anyone know if there would be some sort of output from Delft3D if the model does not converge on any of the timesteps? Or does it just output the results regardless of the accuracy being obtained?

Thanks to anyone in advance emoticon
