ACCELERATION OF FINITE ELEMENT COMPUTATION FOR SEISMIC WAVE PROPAGATION USING GRAPHICS PROCESSING UNIT

Modeling Seismic Wave Propagation Using Graphics Processor Units (GPU)

The main drawback of the seismic modeling in 2D viscoelastic media on a single PC is that simulations with large gridsizes require a tremendous amount of floating point calculations. To improve computation speedup, a graphic processing units (GPUs) accelerated method was proposed using the staggered-grid finite difference (FD) method. The geophysical model is decomposed into subdomains for PML ...

Axisymmetric Scaled Boundary Finite Element Formulation for Wave Propagation in Unbounded Layered Media

Wave propagation in unbounded layered media with a new formulation of Axisymmetric Scaled Boundary Finite Element Method (AXI-SBFEM) is derived. Dividing the general three-dimensional unbounded domain into a number of independent two-dimensional ones, the problem could be solved by a significant reduction in required storage and computational time. The equations of the corresponding Axisymmetri...
