Heterogeneous Domain Decomposition Methods for Fluid-Structure Interaction Problems

In this note, we propose Steklov-Poincaré iterative algorithms (mutu-ated from the analogy with heterogeneous domain decomposition) to solve fluid-structure interaction problems. Although our framework is very general, the driving application is concerned with the interaction of blood flow and vessel wall in large arteries.

Algebraic Domain Decomposition Methods for Highly Heterogeneous Problems

We consider the solving of linear systems arising from porous media flow simulations with high heterogeneities. Using a Newton algorithm to handle the non-linearity leads to the solving of a sequence of linear systems with different but similar matrices and right hand sides. The parallel solver is a Schwarz domain decomposition method. The unknowns are partitioned with a criterion based on the ...

Optimized algebraic interface conditions in domain decomposition methods for strongly heterogeneous unsymmetric problems

Under classical assumptions on the coefficients of the problem (e.g. η − 1 2divb > 0 a.e. in Ω) the matrix A in (2) is definite positive. We solve problem (2) by means of an Optimized Schwarz Method: such methods have been introduced at the continuous level in [4], and at the discrete level in [5]. We design optimized interface conditions directly at the algebraic level, in order to guarantee r...

The Interface Control Domain Decomposition (ICDD) Method for Elliptic Problems

Interface controls are unknown functions used as Dirichlet or Robin boundary data on the interfaces of an overlapping decomposition designed for solving second order elliptic boundary value problems. The controls are computed through an optimal control problem with either distributed or interface observation. Numerical results show that, when interface observation is considered, the resulting i...

Heterogeneous Domain Decomposition for Multi - Scale Problems ∗

The objective of this work is to develop numerical tools useful for the understanding of fundamental phenomena in Blood Flow, including some biochemistry and cellular dynamics. An open problem that may benefit from multi-scale numerical tools is for example the understanding of the relation ship between inflammation and cholesterol plaque. The corresponding topics we address in this paper are (...
