A BDDC preconditioner for a symmetric interior penalty Galerkin method

Susanne C. Brenner, Eun-Hee Park, and Li-Yeng Sung

Abstract

We develop a nonoverlapping domain decomposition preconditioner for the symmetric interior penalty Galerkin method for heterogeneous elliptic problems. The preconditioner is based on balancing domain decomposition by constraints (BDDC). We show that the condition number of the preconditioned system satisfies similar estimates as those for conforming finite element methods. Corroborating numerical results are also presented.
