Extensions of the finite-difference method: irregular grids,
topography, hybrid methods, and absorption

This report summarizes four lines along which the finite-difference
(FD) method has been recently (in 1995/96) extended: (i) irregular
grids, (ii) non-planar free surface, (iii) hybrid methods, and (iv)
approximate absorption treatment. While the former two have been
described in a great detail in a diploma thesis (Oprsal, 1996), and will
be submitted as a methodical paper (Oprsal and Zahradnik, in
preparation), the latter two will be presented together with a practical
application at a conference (Caserta and Zahradnik, 1996).
