AI 中文摘要
本文提出了一种新的算子分裂技术。该方法借鉴了PDE约束域分解中使用的思想,并将其应用于解耦定义在同一几何域上的方程。该方法被应用于线性准静态Biot问题中耦合流动与变形的求解。本文概述了其主要特征,并与孔隙弹性中已确立的固定应力分裂进行了比较。
英文摘要
The present work proposes a new operator splitting technique. The method leverages ideas used in PDE-constrained domain decomposition, adapting them to the objective of decoupling equations defined on the same geometric domain. The methodology is applied here to the resolution of coupled flow and deformation in the linear quasi-static Biot problem. An overview of its main characteristics is provided, also in comparison with the well established fixed-stress split for poroelasticity.
