英文摘要We extended a coupled mode/spectral element method (CSEM hereafter), which can efficiently modeling the seismic waves propagation in the anisotropic D '' region. Using the original PREM and a modified transverse isotropic PREM model in D '' region, we calculated synthetic seismograms with a new PC cluster with 128 CPUs and 160GB memory in the Key Laboratory of Earth Deep Interior. The numerical solution was compared with the analytical solution by normal mode method in order to verify the accuracy of CSEM. Comparison shows that in a broad frequency band (10(-5)similar to 0. 125 Hz) the results of the two methods match very well. Besides, the synthetic seismograms of the transverse isotropic PREM model show obvious arrival time differences between SH and SV components. This proved the capability of CSEM to modeling S wave splitting caused by anisotropic media.
