摘要本文提出了一种新的混合维耦合并行分区分析方法，允许有效的非线性结构分析与选择性部署不同尺寸的元素。用这种方法，一个结构域被分解成分区，并行处理，使用最近开发的双超元素分区方法。单独的分区仅由减小尺寸（1D）或更高尺寸（3D连续体）的元素组成，并且在3D分区的边界处引入1D和3D分区之间的耦合，使得能够减少通信开销。算例验证了该方法的有效性，并证明了该方法在非线性结构分析中的优势。
AbstractThis paper presents a novel mixed-dimensional coupling method for parallel partitioned analysis, allowing efficient nonlinear structural analysis with selective deployment of differently dimensioned elements. With this method, a structural domain is decomposed into partitions that are processed in parallel using a recently developed dual super-element partitioning approach. Individual partitions consist exclusively of reduced dimensioned (1D) or higher dimensioned (3D continuum) elements, and coupling between 1D and 3D partitions is introduced at the boundary of 3D partitions, enabling a reduction in the communication overhead. Several examples are provided to verify the proposed approach and demonstrate its benefits for nonlinear structural analysis.
