چکیده
Spend your time even for only few minutes to read a book. Reading a book will never reduce and waste your time to be useless. Reading, for some people become a need that is to do every day such as spending time for eating. Now, what about you? Do you like to read a book? Now, we will show you a new book enPDFd finite and boundary element tearing and interconnecting solvers for multiscale problems that can be a new way to explore the knowledge. When reading this book, you can get one thing to always remember in every reading time, even step by step.

Inexact Data-Sparse Boundary Element Tearing and Interconnecting Methods
The Boundary Element Tearing and Interconnecting (BETI) methods have recently been introduced as boundary element counterparts of the well–established Finite Element Tearing and Interconnecting (FETI) methods. In this paper we present inexact data–sparse versions of the BETI methods which avoid the elimination of the primal unknowns and dense matrices. However, instead of symmetric and positive...

متن کاملCoupled Boundary and Finite Element Tearing and Interconnecting Methods
We have recently introduced the Boundary Element Tearing and Interconnecting (BETI) methods as boundary element counterparts of the wellestablished Finite Element Tearing and Interconnecting (FETI) methods. Since Finite Element Methods (FEM) and Boundary Element Methods (BEM) have certain complementary properties, it is sometimes very useful to couple these discretization techniques and to bene...
متن کاملRobust FETI solvers for multiscale elliptic PDEs
Finite element tearing and interconnecting (FETI) methods are efficient parallel domain decomposition solvers for large-scale finite element equations. In this work we investigate the robustness of FETI methods in case of highly heterogeneous (multiscale) coefficients. Our main application are magnetic field computations where both large jumps and large variation in the reluctivity coefficient ...
متن کاملRobust Boundary Element Domain Decomposition Solvers in Acoustics
Tearing and interconnecting domain decomposition methods [ 2, 3] are well established for an efficient and parallel solution of various elliptic partial differential equations by using finite and boundary element methods. But in the case of the Helmholtz equation, additional difficulties may appear. Although the global boundary value problem admits a unique solution, local subdomain solvers as ...
