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
