AI Technical Summary
In the analysis of saturated porous media, the limitations of traditional unit shape and order make it difficult to reconcile the contradiction between computational accuracy and efficiency, especially in complex engineering projects where high-precision numerical analysis is difficult to achieve.
A flexible cross-order analysis method for polygonal saturated porous media is adopted. By using second-order elements for refinement in key areas and first-order elements in other areas, and combining polygonal cross-order elements for solution, a smooth transition of cross-scale mesh is achieved by using the scaled boundary finite element method and Biot consolidation theory.
While ensuring computational accuracy, it reduces the computational burden caused by global mesh refinement, alleviates the problems of pore pressure oscillation in first-order elements and increased degrees of freedom in second-order elements, and improves computational efficiency and analysis performance.
