AQWA Input Skill

Input file formats, analysis configurations, DAT file conventions, and mesh quality for ANSYS AQWA. See aqwa for Python API.

File Format Support

LIS Files (Listing Output)

Primary output containing RAOs (amplitude/phase), added mass matrices, damping matrices, wave excitation forces, drift forces.

DAT Files (Data Input)

Input containing hull geometry, mass properties, analysis settings, wave conditions.

MES Files (Mesh)

Mesh definition: panel geometry, node coordinates, panel connectivity.

Analysis Type Configurations

RAO Extraction

aqwa_analysis:
  rao_extraction:
    flag: true
    input_file: "aqwa_results/vessel.LIS"
    vessel_name: "FPSO"
    wave_directions: [0, 45, 90, 135, 180]
    output:
      rao_file: "results/vessel_raos.csv"
      plot_file: "results/rao_plots.html"
      format: "amplitude_phase"  # or real_imaginary

Hydrodynamic Coefficients

aqwa_analysis:
  coefficients:
    flag: true
    input_file: "aqwa_results/vessel.LIS"
    frequencies: "all"  # or specific list [0.1, 0.2, 0.3]
    output:
      added_mass_file: "results/added_mass.csv"
      damping_file: "results/damping.csv"
