ANSYS® AQWA™ is a commercial hydrodynamic package capable of solving the complex wave body interaction problem in the frequency domain.
Fluid structure interaction problems are solved using three dimensional Boundary Integral Equations
Method(BIEM).
BIEM is popularly known as panel method and solves the hydrodynamic radiation and diffraction problem of floating structure interaction with waves (wave body interaction).
The concept involves the solution of the Laplace equation in the fluid domain. The solution procedure basically consists of boundary value problem which requires the application of boundary conditions to solve a desired set of equations, from which velocity potentials are obtained.
SIMULATION USING ANSYS® AQWA™
The programs within the AQWA suite are as follows:
AQWA-LINE: The core solver where 3-D diffraction & radiation analysis of the
modeled structure is carried out and wave forces and response of the structure are calculated. AQWA-LINE also check the hydrostatic stability of the model. It is capable of solving both first order and second order forces in the frequency domain.
For small bodies or structures that are drag dominated, the nonlinear drag force is discarded while using this suite.
AQWA-LIBRIUM: This suite is used to calculate the static equilibrium position and unbalanced force on the structure. AQWA-LIBRIUM is capable of performing the static calculation for free floating as well as moored body.
AQWA-FER: This module is efficient to compute the spectral analysis of coupled or uncoupled response of the floating system. The analysis can be channeled out for both regular and random waves.
AQWA-NAUT: This suite is a time domain solver capable of capturing real time
nonlinear response of free floating and moored body including coupling effects.
