英文摘要In this paper, we introduce a structure-preserving method based on symplectic discrete singular convolution differentiator (SDSCD) for simulating elastic wave fields. In the method presented for solving elastic wave equations, physical space is discretized by singular convolution differentiator, whereas a symplectic difference scheme is used for the time discretization. The computational accuracy and stability of this method have been greatly improved compared with traditional pseudo-spectral method. Numerical results suggest the SDSCD algorithm can suppress effectively numerical dispersion, and it is suitable for modeling the large-scale and long-term seismic wave propagation.
