چکیده
ABSTRACT In this talk we will discuss a nonoverlapping domain decomposition preconditioner for the weakly over-penalized symmetric interior penalty (WOPSIP) method. The WOPSIP method belongs to the family of discontinuous finite element methods. The preconditioner for the WOPSIP method is based on the balancing domain decomposition by constraints methodology. Theoretical results on the condition number estimate of the preconditioned system will be presented along with numerical results. THE DISCRETE PROBLEM

A Nonoverlapping DD Preconditioner for a Weakly Over-Penalized Symmetric Interior Penalty Method
A WEAKLY OVER-PENALIZED SYMMETRIC INTERIOR PENALTY METHOD SUSANNE C. BRENNER , LUKE OWENS , AND LI-YENG SUNG Abstract. We introduce a new symmetric interior penalty method for symmetric positive definite second order elliptic boundary value problems, where the jumps across element boundaries are weakly over-penalized. Error estimates are derived in the energy norm and the norm for both conformi...

In this talk we will discuss several two-level additive Schwarz preconditioners for a weakly over-penalized symmetric interior penalty (WOPSIP) method. The WOPSIP method belongs to the family of discontinuous finite element methods. Theoretical results on the condition number estimate of the preconditioned system will be presented along with numerical results. THE DISCRETE PROBLEM Let Ω be a bo...
متن کاملA Weakly Over-penalized Symmetric Interior Penalty Method for the Biharmonic Problem
We study a weakly over-penalized symmetric interior penalty method for the biharmonic problem that is intrinsically parallel. Both a priori error analysis and a posteriori error analysis are carried out. The performance of the method is illustrated by numerical experiments. 1. Introduction. Recently, it was noted in [9] that the Poisson problem can be solved by a weakly over-penalized symmetric...
