Abstract: An optimization algorithm for hybrid meshes of curved surface was proposed based on Laplacian function．In this algorithm‚the surface boundary was pre-treated first‚then the cell meshes based on interior nodes were re-posited．According to the required size and precision of meshes‚the optimization of meshes was carried out by using Laplacian equation and optimization-based smoothing algorithm． Research results show that‚by using the algorithm‚reasonable hybrid meshes of curved surface and per-
fect optimization result can be obtained with desirable precision．

Key words: triangle mesh, quadrilateral mesh, mesh optimization, Laplacian equation
