Acoustic viscoelastic modeling by frequency-domain boundary element method被引量：1
《Earthquake Science》2017年第2期97-105,共9页Xizhu Guan Li-Yun Fu Weijia Sun 
supported by the National Natural Science Foundation of China (No. 41130418);the Strategic Leading Science and Technology Programme (Class B) of the Chinese Academy of Sciences (No. XDB10010400)
Earth medium is not completely elastic, with its viscosity resulting in attenuation and dispersion of seismic waves. Most viscoelastic numerical simulations are based on the finite-difference and finite-element method...

Exact local refinement using Fourier interpolation for nonuniformgrid modeling被引量：2
《Earth and Planetary Physics》2017年第1期58-62,共5页JinHai Zhang ZhenXing Yao 
supported by the National Natural Science Foundation of China (Grant No.41130418);the National Major Project of China (under grant 2017ZX05008-007);supports from the Youth Innovation Promotion Association CAS (2012054);Foundation for Excellent Member of the Youth Innovation Promotion Association (2016)
Numerical solver using a uniform grid is popular due to its simplicity and low computational cost, but would be unfeasible in the presence of tiny structures in large-scale media. It is necessary to use a nonuniform g...
