Three-dimensional anisotropic seismic wave modelling in spherical coordinates by a collocated-grid finite-difference method
S U M M A R Y To simulate seismic wave propagation in the spherical Earth, the Earth’s curvature has to be taken into account. This can be done by solving the seismic wave equation in spherical coordinates by numerical methods. In this paper, we use an optimized, collocated-grid finitedifference scheme to solve the anisotropic velocity–stress equation in spherical coordinates. To increase the e...
متن کاملGPGPU-Aided 3D Staggered-grid Finite-difference Seismic Wave Modeling
Finite difference is a simple, fast and effective numerical method for seismic wave modeling, and has been widely used in forward waveform inversion and reverse time migration. However, intensive calculation of three-dimensional seismic forward modeling has been restricting the industrial application of 3D pre-stack reverse time migration and inversion. Aiming at this problem, in this paper, a ...
متن کاملGPU Accelerated 2-D Staggered-grid Finite Difference Seismic Modelling
The staggered-grid finite difference (FD) method demands significantly computational capability and is inefficient for seismic wave modelling in 2-D viscoelastic media on a single PC. To improve computation speedup, a graphic processing units (GPUs) accelerated method was proposed, for modern GPUs have now become ubiquitous in desktop computers and offer an excellent cost-toperformance-ratio pa...
متن کاملAn optimized variable-grid finite-difference method for seismic forward modeling
An optimized fourth-order staggered-grid finitedifference (FD) operator is derived on a mesh with variable grid spacing and implemented to solve 2-D velocity-stress elastic wave equations. The idea in optimized schemes is to minimize the difference between the effective wave number and the actual wave number. As expected, this optimized variable-grid FD scheme has less dispersion errors than th...
