Method for high-performance serial and parallel regional block integration of flexibility matrix

The invention discloses a high-performance method for integrating flexibility matrixes by serial and parallel regional blocks. The method comprises the following steps of: integrating a flexibility matrix algorithm by single-thread serial regional blocks and multi-thread parallel regional blocks; the invention discloses a single-thread serial region block integration flexibility matrix algorithm, which is characterized in that a solution domain is divided into a plurality of independent sub-regions, each sub-region independently sets a flexibility matrix and a Lagrange multiplier matrix of a cost region, and a coefficient term matrix of a nonlinear equation set is constructed; the invention discloses a multi-thread parallel regional block integration flexibility matrix algorithm, which is characterized in that a solution domain is divided into a plurality of independent sub-regions, inverse sign information processing of node force boundary conditions required by each sub-region is completed before parallel c
