  A new scheme for communication between overset grids using subcells and
Weighted Essentially Non Oscillatory (WENO) reconstruction for two-dimensional
problems has been proposed. The effectiveness of this procedure is demonstrated
using the discontinuous Galerkin method (DGM). This scheme uses WENO
reconstruction using cell averages by dividing the immediate neighbors into
subcells to find the degrees of freedom in cells near the overset interface.
This also has the added advantage that it also works as a limiter if a
discontinuity passes through the overset interface. Accuracy tests to
demonstrate the maintenance of higher order are provided. Results containing
shocks are also provided to demonstrate the limiter aspect of the data
communication procedure.
