A ctitious domain method for linear elasticity problems
نویسندگان
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 ...

متن کاملCover 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...
