摘要
提出了一种基于多轴扫掠的六面体网格划分算法,首先确定主轴体,并用扫掠法完成主轴体的六面体网格划分;然后修改连接面上移植区的网格节点,作为子轴体的源面网格;最后利用扫掠法来完成子轴体的六面体网格划分。该算法可扩展扫掠法的应用范围,降低扫掠法对实体拓扑结构的要求。网格划分结果表明,该算法稳定可靠,可生成质量较高的六面体网格。
It presents a hexahedral mesh generation method based on multi - axis sweeping. Firstly, it definesand meshes the trunk with sweeping method, modifies the position and connectivity of the nodes on the linking surfaces to align with the graft surfaces. Then it meshes the branch with sweeping method. This method can expand the application of sweeping method and reduce the requirement of solid topology. Examples show that the algorithm is effective, reliable, and that can generate the hexahedral mesh of high quality.
