9503991 Bielak This proposal is concerned with the development of efficient parallel algorithms for the numerical study of wave phenomena that arise when waves propagating within an infinite or semi-infinite medium encounter obstacles in their path. The focus of this proposal is to successfully integrate absorbing boundary techniques, which primarily aim at the reduction of computational domains, with parallel numerical algorithms that exploit distributed memory multiprocessor systems. The ultimate objective is the physical understanding of the modeled system: in this proposal the primary application target is the elastic wave propagation arising in the simulation of the ground motion of large basins.

9503991 Bielak该提案涉及开发用于数值研究波动现象的高效并行算法，当波在无限或半无限介质中传播时遇到其路径上的障碍物。该提案的重点是成功地集成吸收边界技术，其主要目的是减少计算域，利用分布式存储器多处理器系统的并行数值算法。 最终目标是对模型系统的物理理解：在本提案中，主要应用目标是在模拟大型盆地的地面运动时产生的弹性波传播。
