A23. 2d propagation, repeating cartesian coordinates

The purpose of this test is to verify the correct implementation of the repeating grid, both for the first and the second order scheme.
There are output frames which overlay the boundary of the grid. The wave field shown for these frames has to be continuous over the boundary of the computational grid.

The geophysical situation is a gradually varying coastline with a promontory. The plot plfA23a shows the situation.

2 cases are considered:

A23a
the default 2nd order upwind scheme
A23b
the 1st order upwind BSBT scheme

In case A23a the geographical plots are in PostScript format.
