Total FETI
Total FETI - an easier implementable variant of the FETI method for numerical solution of elliptic PDE. A new variant of the finite element tearing and interconnecting (FETI) method for numerical solution of elliptic partial differential equations (PDE) is presented. The basic idea is to simplify inversion of the stiffness matrices of subdomains by using Lagrange multipliers not only for gluing the subdomains along the auxiliary interfaces, but also for implementation of the Dirichlet boundary conditions. Results of numerical experiments are presented which indicate that the new method may be even more efficient than the original FETI.
