چکیده

A ctitious domain method based on boundary Lagrange multipliers is proposed for linear elasticity problems in two dimensional domains. The solution of arising saddle-point problem is obtained iteratively using MINRES method with a positive deenite block diagonal preconditioner which is based on a fast direct solver for diiusion problems. Numerical experiments demonstrate the behavior of considered method.

Eecient Iterative Solution of High Frequency Acoustic Scattering Problems

A ctitious domain method for the solution of the 3D Helmholtz equation with absorbing boundary conditions is considered. The nite element discretization leads to a large-scale linear system, which is solved by the algebraic ctitious domain method with GMRES iterations. With this approach the iterations can be realized in a low-dimensional subspace and thereby the partial solution method can be ...

A Parallel Fictitious Domain Method for the Three-Dimensional Helmholtz Equation

The application of ctitious domain methods to the three-dimensional Helmholtz equation with absorbing boundary conditions is considered. The nite element discretiza-tion is performed by using locally tted meshes, and algebraic ctitious domain methods with separable preconditioners are used in the iterative solution of the resultant linear systems. These methods are based on embedding the origin...

Two - Level Schwarz Method for Unilateralvariational Inequalitiesp

Numerical solution of variational inequalities of obstacle type associated with second-order elliptic operators is considered. Iterative methods based on the domain decomposition approach are here proposed for discrete obstacle problems arising from the continuous, piecewise linear nite element approximation of the diierential problem. A new variant of the Schwarz methodology, called the two-le...

Cover interpolation functions and h-enrichment in finite element method

This paper presents a method to improve the generation of meshes and the accuracy of numerical solutions of elasticity problems, in which two techniques of h-refinement and enrichment are used by interpolation cover functions. Initially, regions which possess desired accuracy are detected. Mesh improvment is done through h-refinement for the elements existing in those regions. Total error of th...
