摘要
根据三维形体的物理特征确定网格划分的加密规则,提出基于Delaunay剖分的动态节点单元一体化三维网格自适应生成算法,通过选取的节点集来确定最佳节点,对节点集进行Delaunay三角剖分,并对特征集中区域进行局部加密。将该方法应用于水泥熟料流动冷却工程模拟分析中,实验结果表明该方法能够真实反映研究对象几何形体特征及实现其物理特征的网格疏密分布,为研究熟料划分后各微元热平衡关系提供较好的基础。
Determines the grid division encryption rule according to the three dimensional entity physical characteristic, a algorithm proposed based on the Delaunay triangulation.Through the selection nodes determined the best node, carries on Delaunay triangulation to the nodes, and carry on the local mesh refinement of the characteristic centralized region.The experiment applies in the cement clinker flowing cooling project simulation analysis, finally indicated can really reflect the original geometry physique the characteristic, simultaneously can realize its physical characteristic grid density distribution.The method provides the good foundation to study the cell thermal equilibrium relations.
