Wave Interaction Analysis


WAMIT is a computer program based on the panel method for analyzing hydrodynamic interactions with floating or submerged bodies, in the presence of ocean waves. The basic underlying theory is the linear frequency-domain potential representation of the fluid motion.

All first-order oscillatory quantities and second-order mean forces are computed in a consistent and efficient manner. Substantial efforts have been devoted to the development and improvement of this program, with many unique features:

  • Arbitrary three-dimensional body geometry is prescribed by rectangular and/or triangular panels.
  • Efficient set-up and solution of the linear system of equations are provided by refined subroutines for the Green function and a special iterative solver.
  • Outputs include the added-mass and damping coefficients, Haskind exciting forces/moments, diffraction pressure exciting forces/moments, body motions in waves with optional specification of external force/moment constraints, pressures and fluid velocities on the body and at specified field points, free-surface elevations, and drift forces/moments evaluated by momentum conservation and pressure integration.
  • Options include irregular-frequency removal, analysis of multiple interacting bodies, and hydroelastic analysis using generalized modes.
