چکیده
Since the introduction of Finite Element Tearing and Interconnecting (FETI) by 10 Farhat and Roux in 1991, the method has been recognized to be an efficient parallel technique 11 for the solution of partial differential equations. In 2003 Langer and Steinbach formulated its 12 boundary element counterpart (BETI), which reduces the problem dimension to subdomain 13 boundaries. Recently, we have applied both FE I and BETI to contact problems of mechanics. 14 In this paper we numerically compare their variants bearing the prefix Total (TFETI/TBETI) 15 on a frictionless Hertz contact problem and on a realistic problem with a given friction. 16

We propose and analyze a hybrid discontinuous Galerkin method for the solution 10 of incompressible flow problems, which allows to deal with pure Stokes, pure Darcy, and 11 coupled Darcy-Stokes flow in a unified manner. The flexibility of the method is demonstrated 12 in numerical examples.

In this paper we present a stable boundary element tearing and interconnecting 6 domain decomposition method for the parallel solution of the electromagnetic wave equation 7 with piecewise constant wave numbers. In particular we consider stable boundary integral 8 formulations and generalized Robin type transmission conditions to ensure unique solvability 9 of the local subproblems. Numerical r...
