Oscillating-body dynamics<br />
Several degrees of freedom<br />
• Each body has 6 degrees of freedom<br />
• A WEC may consist of n bodies (n >1)<br />
All these modes of oscillation interact with each<br />
other through the wave fields they generate.<br />
Number of dynamic equations = 6n<br />
The interference between modes affects:<br />
• added masses<br />
• radiation damping coefficients<br />
Hydrodynamic coefficients<br />
accordingly.<br />
A ij , B ij<br />
are defined<br />
They can be computed with commercial software<br />
(WAMIT, …).<br />
