Description:
We propose and study an iterative substructuring method for an $h$ - $p$ Nitsche-type discretization, following the original approach introduced in Bramble et al. Math. Comp. 47(175):103–134, ( 1986 ) for conforming methods. We prove quasi-optimality with respect to the mesh size and the polynomial degree for the proposed preconditioner. Numerical experiments assess the performance of the preconditioner and verify the theory.
