| dc.description.abstract | We present a finite-volume method for the modeling of wave propagation on irregular
triangular grids. This method is based on an integral formulation of the wave equation
via Gauss's theorem and on spatial discretization via Delaunay and Dirichlet tessellations. We derive the equations for both SH and P-SV wave propagation in 2-D. The
method is of second-order accuracy in time. For uniform triangular grids it is also
second-order accurate in space, while the accuracy is first-order in space for nonuniform
grids.
This method has an advantage over finite-difference techniques because irregular
interfaces in a model can be represented more accurately. Moreover, it may be computationally more efficient for complex models. | en_US |
