A Locking-free and Loosely Coupled Robin-Robin Scheme for Fluid-Poroelasticity Interaction
Wenlong He, Thomas Wick, Xiaohe Yue +2
We study a fluid-poroelasticity interaction (FPSI) problem coupling the unsteady Stokes equations with the fully dynamic Biot system. A major challenge in such problems is to desig…
Error Analysis of Krylov Subspace approximation Based on IDR() Method for Matrix Function Bilinear Forms
Qianqian Xue, Xiaoqiang Yue, Xian-Ming Gu
The matrix function bilinear form, namely , appears in many scientific computing problems, where , $A \in \…
An Unconditionally Stable Explicit Robin-Robin Partitioned Scheme for Fluid-Structure Interaction
Shihan Guo, Ping Lin, Yifan Wang +2
We propose an explicit partitioned (loosely coupled) scheme for fluid structure interaction (FSI) problems, specifically designed to achieve high computational efficiency in modern…
A Fully Parallelizable Loosely Coupled Scheme for Fluid-Poroelastic Structure Interaction Problems
Shihan Guo, Yizhong Sun, Yifan Wang +2
We investigate the fluid-poroelastic structure interaction problem in a moving domain, governed by Navier-Stokes-Biot (NSBiot) system. First, we propose a fully parallelizable, loo…
