WAMIT

WAMIT is a scientific and technical tool designed to help make analysis of the floating and submerged bodies when ocean waves are present. The program relies on the linear and second-order potential theory and employs the Boundary Integral Equation method for the purpose of solving the velocity potential and fluid pressure on submerged bodies.

According to the developer, scientists can perform various types of analysis and obtain separate solutions for the diffraction problem. Regardless of the number of solutions, they can be carried out at the same time and provide answers on the effects of incident waves on the body. Scientists can learn more about the effects of the pressure and fluid velocity, the mean drift forces as well as the involved response-amplitude operators.

The tool can provide traditional solutions that rely on the low-order method which involves geometry represented by quadrilateral panels, whereas the velocity is simply assumed. The program can also employ a high-order method where users can define the geometry of the bodies exactly or approximately. The latter method is based on represented by continuous B-splines.

When used for the analysis of multiple bodies, the tool accounts for the hydrodynamic interaction between objects and enables users to define additional physical phenomena, such as wavemakers, motion of hinged structures or various wave-energy converters, for instance.
