浮球的振荡运动：一个 计算流体力学（CFD）问题

(1)

\mathbf{f} = \mathbf{n} \cdot \left\{ -p\mathbf{I}+\left(\mu\left(\mathbf{\nabla} \mathbf{u}_{\text{fluid}}+\left(\mathbf{\nabla} \mathbf{u}_\text{fluid}\right)^{T}\right)-\frac{2}{3}\mu\left(\mathbf{\nabla}\cdot\mathbf{u}_{\text{fluid}}\right)\mathbf{I}\right)\right\}

(2)

\begin{align}
F_z &= m g + m\frac{d v_{s}}{d t}\\
v_s &= \frac{d u_s}{d t}
\end{align}

(3)

\left.\mathbf{u_{\text{mesh}}}\right|_{\text{Interfacing boundaries}} = \left(0,u_{\text{s}}\right)

(4)

\left.{\mathbf{u}_{\text{fluid}}}\right|_{\text{Interfacing boundaries}} = \left(0,v_s\right)

6.0 版本中新增磁机械力接口可以直接将两者进行耦合，参考案例：http://cn.comsol.com/model/102811
