In aim solver , the convergence rate depends on spectral properties of the aim matrix , and the near - zone threshold distance has a dramatic impact on the memory and cpu time . a poorly conditioned matrix occurs through aim when a smaller near - zone 另外,自適應積分方法計算中,在保證計算精度的條件下,較小的耦合距離將極大減小內(nèi)存需求和計算的復雜度,但同時誤差積累也導致矩陣的性態(tài)變壞。
It presents the angle of the two normal vectors formed by the new and the old triangles , the threshold distance and the principle of maximal - minimal angle in the paper to constrain the growing of the triangles , so as to reduce the searching area , improve the correctness and confirm the quality of the mesh 該方法通過引入三角形法向量夾角、閾值距離以及最小內(nèi)角等幾個參數(shù)對三角形的生長進行約束,同時利用生長法,對空間中的離散點集進行逐步三角劃分,直至所有三角形擴展完畢。
