摘要 断层切割算法在三维数值流形方法应用于工程模拟中具有重要意义。本文提出了故障切割算法的初步方法，包括数据结构、故障切割程序和一些基本计算算法。首先，物理元素和数学覆盖的数据结构分别被提出为单链表和链表数组。这降低了算法的复杂性并提高了将物理元素连接到盖子时的效率。其次，提出了记录每两个断层之间切割痕迹的策略，以确保模型与实际情况相符。该策略还降低了复杂性并提高了效率。第三，数学覆盖和物理元素独立地进行所有故障的切割，以处理多块形式的完整切割实例和不完整切割实例，而不形成任何新的无理块。最后，四...
AbstractThe fault cutting algorithm is important when applying the three-dimensional numerical manifold method to engineering simulation. This paper presents a primary approach to the fault cutting algorithm, including data structures, fault cutting procedures, and some basic computing algorithms. First, the data structures of the physical elements and mathematical covers are proposed as single linked lists and linked list arrays, respectively. This reduces the complexity of the algorithm and increases the efficiency when connecting physical elements to covers. Second, a strategy of recording cutting traces between every two faults to ensure that the model agrees with the actual situation was proposed. This strategy also reduces the complexity and improves the efficiency. Third, the mathematical covers and physical elements are cut with all faults independently to process complete cutting instances in a multiblock form and incomplete cutting instances without forming any new irrational block. Finally, fou...
