This process is independent of the surface mapping, so the size and shape of the elements can be controlled more easily. Then some post-processing is applied to enhance the quality of the generated grid.

• 鉴于非结构网格在处理复杂形体表面的优势,本文采用阵面推进法直接在三维表面上生成非结构表面网格,采取有效的算法处理了空间三角形网格单元生成的有效性判断,并对网格进行了优化处理,大大提高了原始网格的质量。
