A Fully Implicit Domain Decomposition Based ALE Framework for Three-dimensional Fluid-structure Interaction with Application in Blood Flow

Due to the rapid advancement of supercomputing hardware, there is a grow-ing interest in parallel algorithms for modeling the full three dimensional interaction between the blood flow and the arterial wall. In [4], Barker and Cai developed a parallel framework for solving fluid-structure interaction problems in two dimensions. In this paper, we extend the idea to three di-mensions. We introduce and study a parallel scalable domain decomposition method for solving nonlinear monolithically coupled systems arising from the discretization of the coupled system in an arbitrary Lagrangian-Eulerian framework with a fully implicit stabilized finite element method. The investi-gation focuses on the robustness and parallel scalability of the Newton-Krylov algorithm preconditioned with an overlapping additive Schwarz method. We validate the proposed approach and report the parallel performance for som
