Abstract

Modeling of wave propagation in a realistic geological environment needs a numerical scheme able to handle complex shapes and geometries. Finite difference scheme based on a generalization of the rotated staggered grid method can be used for modeling of elastic waves on curvilinear grid. This scheme has been validate with classical analytical solutions and used to simulate elastic wave propagation in complex geometries. The proposed method is simple and computationally performing.
