--- Welcome to the official ADCIRCWiki site! The site is currently under construction, with limited information. ---
For general information, see the ADCIRC site, ADCIRC FAQ, or the ADCIRC Wikipedia page. For model documentation not yet available on the wiki, see the ADCIRC site. New content is being continuously added to the ADCIRCWiki, and material from the main ADCIRC site will be gradually transitioned over to the wiki.

ADCIRC File Formats

Input Files Contributor needed

Required: Every ADCIRC run requires the following two input files:

  • fort.14 file - Grid file: Defines the ADCIRC triangular finite element grid
  • fort.15 file - Parameter file: Sets runtime parameters, frequency-dependent boundary forcing, and output options

Optional, frequently used, depending on simulation configuration:

  • fort.13 file - Nodal Attribute file: Defines parameters (e.g., Mannings N, canopy cover) that can be set at specific nodes.
  • fort.22 file - Wind forcing file. The specific format of this file depends on the wind input format. See the NWS parameter in the fort.15 file description.

Optional, depending on simulation forcing configuration:

  • For coupled SWAN runs:
    • fort.26 file - SWAN parameter file. Same format as a traditional SWAN input file, but with "SWAN unstructured grid" commands specific to the coupled ADCIRC+SWAN code.
    • swaninit file - SWAN init file. This is the same as in a traditional SWAN run.
