Abstract
The focus of this paper is a detailed description of the incorporation of absorbing boundary conditions in the symbolic solution of the two- dimensional elastic wave equation. This symbolic solution forms the basis for the spectral time-marching technique, which is also described. Appli- cation of the absorbing boundary conditions necessitates the employment of a spatial spectral discretization, yielding an algorithm whose accuracy is balanced in time and space. The kernel operation of this time-stepping algorithm is matrix multiplication, efficiently implemented on existing supercomputers . 1 Introduction introduce
