Auxiliary space preconditioners for linear elasticity based on generalized finite element methods
arXiv:1003.2475
Abstract
We construct and analyze a preconditioner of the linear elastiity system discretized by conforming linear finite elements in the framework of the auxiliary space method. The auxiliary space preconditioner is based on discretization of a scalar elliptic equation with Generalized Finite Element Method.
