WAMIT® is the most advanced set of tools available for analyzing wave interactions with offshore platforms and other structures or vessels. Since the announcement of Version 1 in 1987 at MIT, WAMIT has gained widespread recognition for its ability to analyze complex structures with a high degree of accuracy and efficiency. Over the subsequent years WAMIT has been licensed to more than 100 industrial and research organizations worldwide. Upgrades have been issued at approximately two-year intervals, with many enhancements.
WAMIT® Version 6, which has been available since 2000, represents a quantum jump in capabilities, including a higher-order method of solution and various options for defining the geometry. Version 6S has the additional capability of complete second-order nonlinear analysis in bichromatic and bidirectional waves.
Subsequent updates have introduced the option to link WAMIT with the Relational Geometry Kernel of the CAD program MultiSurf, facilitating a seamless transition from design to hydrodynamic analysis; to analyze internal tanks with free surfaces coupled with the dynamics of vessels; to evaluate the mean drift forces and moments on structures from the momentum flux through a control surface surrounding each structure. A complete chronological list of updated features is in Chapter 1 of the User Manual.
WAMIT® Version 6.4 is now available with additional extensions and updates from Version 6.3. These include options to trim waterlines, to automatically represent control surfaces and interior free surfaces, to input response-amplitude operators (RAO) from users' post-processors, and to use more flexible inputs for multi-body analysis. Further details are provided here, and in the User Manual. Most of these options can be tested using the Demonstration Version of WAMIT®.
