NX高级仿真中如何利用“曲面包裹流体域”命令自动抽取流体域？

何以醉

如题，“曲面包裹流体域”命令是否可以抽取任何几何体内的流体域？复杂装配体内流体域抽取怎么操作呢？官网上有类似操作，但截面模糊，我试过用该命令提取简单几何体内型腔流体域，但没成功。麻烦有经验的大侠指导下该命令详细用法，特别是对复杂装配体。

Surface Wrapping Technology
Rapidly create fluid domain geometry in just a matter of seconds. NX CAE includes powerful surface wrapping technology that rapidly extracts complex interior or exterior surface volumes for CFD analysis. Furthermore, the new fluid domain geometry is associated to the base design, so you can quickly update your analysis model whenever the design changes.
