一个3-D有限差分弹性波传播的代码，采用了一些先进的计算和物理为基础的增强已经开发出来。这些增强功能包括全三维弹性、粘弹性和地形建模（正在添加各向异性功能）、低级优化、传播和变密度网格、杂交和并行化。该代码利用高性能计算和大规模并行处理的优势，使地震问题的三维全物理模拟成为可能。该计算工具将用于生成SEG/EAEG声学数据集的弹性子集。将比较声波和弹性数据，以检查传统处理的缺陷，并测试使用弹性数据作为地震成像辅助手段的有效性。
A 3-D finite-difference elastic wave propagation code that incorporates a number of advanced computational and physics-based enhancements has been developed. These enhancements include full 3-D elastic, viscoelastic, and topographic modeling (anisotropic capabilities arc being added), low-level optimization, propagating and variable density grids, hybridization, and parallelization. This code takes advantage of high performance computing and massively parallel processing to make 3-D full-physics simulations of seismic problems feasible. This computational tool will be used to generate an elastic subset of the SEG/EAEG acoustic data set. The acoustic and elastic data will be compared to examine pitfalls with traditional processing, and to test the effectiveness of using elastic data as an aid to seismic imaging.
