| Abstract: | The newly emerged cut-paste algorithm in overlapping grid technique is investigated and enhanced here for automatic DRAGON grid generation, with label close-up and reorganization techniques for hole-boundaries between structured grids. The enhancements are mainly on hole-mapping and orphan grid deletion. A universal code based on this algorithm is built up with complex examples in two dimensional cases for validation. The results reveal that a very automatic and stable degree is achieved for high-quality DRAGON grid generation. |
