Investigation and enhancement of hole mapping method

  • 摘要: 针对传统洞映射方法存储大的缺点,对"广义封闭"的概念进行扩展,提出了最小洞映射方法,该方法允许挖洞曲面结束于网格截断面,有效缩小了洞映射区域,节省了存储开销.对适用于广义封闭的洞映射单元识别方法进行了分析,指出了用物面信息判断映射单元属性可靠性较差.发展了一种新的特别适合广义封闭问题的识别方法:"Inverse mark",使用计算网格结点信息自动识别洞外单元,再作为初始点在网格内部推进.研究表明:"Inverse mark"方法计算效率高,可靠性好,自动化程度高,有效提高了重叠网格方法对缝隙等局部复杂结构的适应性
