Abstract

Full wave form modeling techniques in 3D complex heterogeneous elastic media axe computationally expensive, even on today’s largest supercomputers. In contrast asymptotic techniques only compute a small subset of the wave field, but can be very fast. Using asymptotic methods in combination with full wave form techniques can speed up the overall computation. I use a particular asymptotic method to compute dynamically the progressingly active computational domain for a parallel full wave form finite difference technique. This leads to an overall decreased computational runtime. This computational technique is applied to simulation in a industrially oriented oil/gas bearing subsruface model as well as to simulation of earthquake related scientific scenarios.
