This paper presents an improved domain decomposition method for 3‐dimensional triangular and quadrilateral surface mesh generation .T he key techniques used in this method include the establish‐ment of the topology of triangular facets ,the facet grouping and determination of the feature face ,the node generation along spatial curve ,the boundary merging of the domain ,the determination of best split‐ting line and the mesh smoothing ,etc .The detail introduction of these techniques is given in this paper . The proposal method in the paper is reliable and efficient for surface mesh generation with high mesh quality .The examples of surface mesh generation are also given to demonstrate the robustness of the method .
