Subdomain Modeling in ADCIRC

What is it? An exact reanalysis technique for storm surge and tides that enables the assessment of local subdomain changes with less computational effort than would be required by a complete resimulation of the full domain. So long as the subdomain is large enough to fully contain the altered hydrodynamics, changes may be made and simulations performed within it without the need to calculate new boundary values.

Subdomain modeling is now built into the official ADCIRC release, beginning with v51.42 (as of Jan 28, 2015).

Subdomain ADCIRC+SWAN v53

The latest user guide and scripts are available below:

User guide: sa-guide-17.pdf
Python 2 scripts: sa-scripts-18.zip (as of Aug 14, 2018)

• Subdomain modeling works with both ADCIRC and coupled ADCIRC+SWAN runs.
• A remapping script is now included for subdomains whose boundary node numbers differ from those of the full domain.
• Source repository on GitHub can be found here: https://github.com/alperaltuntas/subdomainPy

Other tools for working with subdomains

dev.adcirc.io

• Open and render fort.14 files in 2D
• Open and render fort.63 files
• Step through timesteps of fort.63
• Plot elevation timeseries for individual nodes

subdomain.adcirc.io

• Open and render fort.14 files in 2D
• Draw/edit an ellipse on top of rendered mesh
• Save a shapefile in *.e14 format

plot.adcirc.io

• Open and plot elevation timeseries for individual nodes in a fort.63 file
• (Note that you need to go through the "File" menu to load a fort.63 file, the giant "Add dataset" button does nothing)

Additionally, all of the code for those tools can be found in these repositories: https://github.com/orgs/adcirc-io/repositories
