This repository contains the toolbox for the automated creation of the SWAN wind wave model configurations for the local domains.
To run the SWAN simulation for the new domain:
from core.simulation_case.case import Case
case = Case('domain_description.json')
case.prepare_case()
case.run()The output is automatically converting to NetCDF4 format.
- Create JSON the describes the configuration (see the examples in 'cases' folder)
- Set the coordinates and paths to the data. The possible values of the BDC sources can be seen here. By default, the global wave reanalysis from NOAA is used.
- The source of bathymetry data can be obtained from GEBCO.

}CDO toolbox installation (Win10):
- Install Windows Subsystem for Linux (as admin):
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
-
Install Ubuntu Linux from Microsoft Store, restart the PC.
-
Install CDO package as:
ubuntu
sudo apt-get update
sudo apt-get install -y cdo
- Fix Qt5/WSL1 issue with:
sudo strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
-
(optional) If you want to upload the ERA5 wind data in automated way, use the instruction to obtain the CDS API key and pun it to the $HOME/.cdsapirc.
-
(optional) To run the SWAN in parallel mode - install MPICH2 for Windows.
