These are the proceedings of the 20th international conference on domain decomposition methods in science and engineering. Domain decomposition methods are iterative methods for solving the often very large linearor nonlinear systems of algebraic equations that arise when various problems in.

We introduce a new class of methods, denoted as Truncated Conjugate Gradient(TCG), to solve the many-body polarization energy and its associated forces in molecular simulations (i.e. molecular dynamics (MD) and Monte Carlo). The method consists in a fixed number of Conjugate Gradient (CG) iterations. TCG approaches provide a scalable solution to the polarization problem at a user-chosen .   As observed from numerous numerical experiments carried out with the Lanczos biconjugate A-orthonormalization methods, it has been numerically demonstrated that this family of solvers shows competitive convergence properties, is cheap in memory as it is derived from short-term vector recurrences, is parameter-free, and does not require a symmetric preconditioner like other .

Closer to the solution: Iterative linear solvers. we have observed a growing interest in the ‘parameter-free’ Krylov subspace methods for unsymmetric systems.

Saad () has written a. This book presents a unifying theoretical framework for iterative solvers for linear systems. The focus is on parameter-free methods, i. methods that can be applied without a priori knowledge of inner properties of the systems.

Despite the generality of the approach convergence estimates and geometrical properties can be derived. In order to provide generallyap plicable iterative linear solvers for the communityof scientific computing the LINSOL program package has been designed.

The focus of this package is on portability, Parameter-free iterative linear solvers book and on an efficient implementation on massivelyp arallel sys- tems. LINSOL uses iterative solvers as basic methods that are state of the by: 2. The generalized conjugate gradient method proposed by Axelsson is studied in the case when a variable-step preconditioning is used.

This can be the case when the preconditioned system is solved approximately by an auxiliary (inner) conjugate gradient method, for instance, and the thus-obtained quasi residuals are used to construct the next search vector in the outer generalized cg-iteration Cited by: This chapter presents a new product triangular iterative method for solving nonsymmetric linear systems of equations with positive real coefficient matrices.

The triangular operators of this iterative method use the skew-symmetric part of the initial matrix. The chapter presents the convergence analysis for. LINSOL is an iterative linear solver package (solving Ax=b) with direct solvers as preconditioners.

The program package is adapted to the application of sparse matrices, but can be efficiently. The design of PDE black-box solvers (for nonlinear systems of elliptic and parabolic PDEs) needs many compromises between efficiency and robustness which we call ‘Numerical Engineering’.

The requirements for a black-box solver are formulated and the way how to meet them is presented, guided by many years of practical experience in the. Grosz L. () VECFEM-Solver for Non-Linear Partial Differential Equations. In: Houstis E.N., Rice J.R., Gallopoulos E., Bramley R.
