SPECFEM3D_GLOBE is a spectral-element application enabling the simulation of global seismic wave propagation in 3D anelastic, anisotropic, rotating and self-gravitating Earth models at unprecedented resolution. A fundamental challenge in global seismology ...
 
Simulations of Global Seismic Wave Propagation for 3-D Earth Model
Found in: High Performance Computing and Grid in Asia Pacific Region, International Conference on
By Seiji Tsuboi, Dimitri Komatitsch, Chen Ji, Jeroen Tromp
Issue Date:July 2004
pp. 496-501
We use a Spectral-Element Method implemented on the Earth Simulator in Japan to simulate broadband seismic waves generated by various earthquakes. The spectral-element method is based on a weak formulation of the equations of motion and has both the flexib...
 
A 14.6 billion degrees of freedom, 5 teraflops, 2.5 terabyte earthquake simulation on the Earth Simulator
Found in: SC Conference
By Dimitri Komatitsch, Seiji Tsuboi, Chen Ji, Jeroen Tromp
Issue Date:November 2003
