UN CO RR EC TE D PR O O F 1 A Parallel Monolithic Domain Decomposition Method 2 for Blood Flow Simulations in 3 D 3

چکیده
We develop a parallel scalable domain decomposition method for the simulation 9 of blood flows in compliant arteries in 3D, by using a fully coupled system of linear elasticity 10 equation and incompressible Navier-Stokes equations. The system is discretized with a finite 11 element method on unstructured moving meshes and solved by a Newton-Krylov algorithm 12 preconditioned with an overlapping additive Schwarz method. We focus on the accuracy and 13 parallel scalability of the algorithm, and report the parallel performance and robustness of the 14 proposed approach by some numerical experiments carried out on a supercomputer with a 15 large number of processors and for problems with millions of unknowns. 16

UN CO RR EC TE D PR O O F 1 Stable BETI Methods in Electromagnetics
In this paper we present a stable boundary element tearing and interconnecting 6 domain decomposition method for the parallel solution of the electromagnetic wave equation 7 with piecewise constant wave numbers. In particular we consider stable boundary integral 8 formulations and generalized Robin type transmission conditions to ensure unique solvability 9 of the local subproblems. Numerical r...

The Chimera Method developed originally in [1, 19, 20] simplifies the construction 16 of computational meshes about complex geometries. This is achieved by breaking 17 the geometries into components and generating independently a series of different 18 meshes. This enables one a great flexibility on the choice of the type of elements, 19 their orientations and local mesh refinement. The compone...

Elliptic variational inequalities with multiple bodies are considered. It is assumed 7 that an active set method is used to handle the nonlinearity of the inequality constraint, which 8 results in auxiliary linear problems. We describe two domain decomposition methods for solv9 ing such linear problems, namely, the FETI-FETI (finite element tearing and interconnecting) 10 and hybrid methods, wh...
