In this paper we consider second order elliptic partial differentialequations with highly varying (heterogeneous) coefficients on a two-dimensionalregion. The problems are discretized by a composite finite element (FE) anddiscontinuous Galerkin (DG) Method. The fine grids are in general nonmatchingacross the subdomain boundaries, and the subdomain partitioning does not needto resolve the jumps in the coefficient. A FETI-DP preconditioner is proposedand analyzed to solve the resulting linear system. Numerical results arepresented to support our theory.
