Abstract
En 中文
Current mainstream engineering simulation software struggles to generate high-quality quadrilateral meshes during the preprocessing stage, and achieving such meshes typically relies on numerical solvers. To enable efficient and high-quality quadrilateral mesh generation for complex geometries in open-source environments, this paper proposes a lightweight quadrilateral mesh reconstruction method. The method first takes a triangular mesh model as input and parameterizes it onto a 2D plane and performs polygonal layout decomposition using directional constraints. A greedy propagation strategy is then employed to assign uniform subdivision parameters to layout boundaries, replacing global integer programming. Finally, quadrilateral mesh templates are embedded to complete the mesh generation. The entire process avoids reliance on numerical solvers. Experiments on publicly available benchmark models demonstrate that, even without using solvers, the generated meshes achieve quality comparable to or better than mainstream approaches, providing a low-cost, high-accuracy preprocessing solution for engineering simulations.
