虚拟水池试验系统中船体曲面和网格自动生成技术

Technique study on automatic generation of the hull surfaces and mesh in virtual pool experiment system

为推动CFD技术在船舶水动力学领域的更高层面的广泛应用,中国船舶科学研究中心开发了舰船综合水动力虚拟水池试验技术系统。该系统为了减轻传统CFD分析中的重复性工作,实现了船体复杂三维曲面和全域结构化网格的自动生成。本文对系统中三维曲面和网格自动生成技术进行详细讨论。

To promote CFD technology applications in ship hydrodynamics field with a higher level and a wide range, CSSRC developed the Ship integrated hydrodynamic virtual pool experiment system. In order to reduce the repetitive work in traditional CFD analysis,the system realize the automatic generation of the hull complex 3D surfaces and global structured mesh. This paper discussed these techniques in detail.
