英文摘要：

Unstructured mesh generation technique is investigated for two dimensional flow with freesurface. Delaunay method and local advancing front approaches are used to cope with element deformation around moving boundaries. Boundary edge splitting and merging approach are proposed to optimize the distribution of boundary points. Qualities of local regenerated elements increase. Numerical examples of flow around deformed droplet induced by shock indicate the validity and robustness of the developed methods.
