假设不可压缩、无粘性且无旋转的流动，流体运动可以通过标量场 φ 建模，称为速度势，并且 u = ∇φ。流体质量守恒可以写成拉普拉斯问题 ∇φ = 0 。假设浮体运动较小且波高较小，自由表面的边界条件可以线性化。由此产生的问题是完全线性的，并且可以在频域中求解。
Assuming an incompressible, inviscid and irrotational flow, the fluid motion can be modeled by a scalar field φ, called velocity potential and such that u = ∇φ. The conservation of the mass of the fluid can be written as a Laplace problem ∇φ = 0 . Assuming small motions of the floating body and small wave heights, the boundary condition at the free surface can be linearized. The resulting problem is fully linear and can be solved in the frequency domain.
