Postdoc: Parallel Computations for Wave Propagation Modeling of Large Basins

[503991] Bielak这一提议涉及发展有效的并行算法，用于在无限或半无限介质中传播的波在其路径上遇到障碍物时产生的波现象的数值研究。该建议的重点是成功地将吸收边界技术与利用分布式内存多处理器系统的并行数值算法相结合，吸收边界技术主要旨在减少计算域。最终目标是对模拟系统的物理理解：在本建议中，主要应用目标是模拟大型盆地地面运动中产生的弹性波传播。

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.
