“…However, compared to the direct algorithm, the more complex the model, the more time our algorithm saves. In addition, the qualities of meshes conforming to curves discretization results are given to illustrate that meshes are suitable for subsequent numerical analysis, such as FEM (Nayroles et al , 1992) and BEM (Qin et al , 2010; Brebbia et al , 1984; Zhang et al , 2017).…”

“…The quad-tree and triangular grid are commonly used as background grid in two-dimensional (Owen and Saigal, 2015), and the octree and tetrahedral grid are popularly applied in three-dimensional (Borouchaki et al , 2015; Zhang et al , 2017). In this paper, we use octree as three-dimensional background grid.…”

“…To achieve high computational accuracy, the integrals with singularity in the DBEM must be accurately computed [9,12,15,[19][20][21][22][23][24][25][26][27]. In this section, the singular integral is gradually computed through three steps.…”

“…Firstly, we compute the distance r P 1 � P 1 P ′ , r P 2 � P 2 P ′ , and r P 3 � P 3 P ′ . en, we calculate the SIFs using equation (27) through the CODs of P 1 , P 2 , and P 3 . We denote the results as K p 1 , K p 2 , and K p 3 .…”

“…The boundary element method [1 -6] has been applied in many areas [7][8][9][10][11][12] because of its high accuracy and boundary-only discretization. Compared with the finite element method (FEM), BEM can obtain very high accuracy with much fewer elements on the boundary.…”
