Abstract
This paper mainly discusses a general flux conservation interpolation algorithm for patched grid applying to the "duplicate searching" process of patched grid,which offers an efficient and reliable interpolation approach for patched grid's pre-processing. The algorithm makes use of the "polygon cutting" theory in graphics as well as the curve integral formula flexibly to get the intersected polygon and their areas on patching section, and is easily to implement with low complexity and good robustness, and is suitable for both structured and unstructured grids problems. Experiment results show that even in the case of large grids number with complicated patching area,this patched grid interpolation algorithm can still achieve ideal result.关键词
