Abstract
PurposeThe paper aims to propose a generation approach for unstructured surface mesh to speed up mesh generation.Design/methodology/approachThe paper proposes a lightweight interactive generation approach for unstructured surface mesh and presents several key technologies to support this approach.FindingsThe experimental results show that the proposed approach is feasible for unstructured meshes and it can accelerate the mesh generation process.Research limitations/implicationsMore geometric defects should be covered, and more convenient and efficient interactive means need to be provided.Practical implicationsThe proposed approach and key technologies are implemented in NNW-GridStar.UG, which is the unstructured version of the mesh generation software of National Numerical Windtunnel (NNW).Originality/valueThis paper proposes a lightweight interactive approach for unstructured surface mesh generation, which can speed up mesh generation.
