Accelerating calculation for NDE simulator of FEM by using multi-GPGPUs and its procedures for evaluation

A parallel mixed 3D grid/explicit FEM scheme for computing elastic wave propagation on a GPU using an irregular mesh

“…Progress has also been made leveraging parallel clusters to greatly improve the ultrasonic NDE simulation time of the elasto-dynamic finite integration technique (EFIT) [4] Graphical Processing Units (GPUs) offer a substantial benefit for naturally parallelized computations in ultrasonic wave propagation. In [5] the authors showed dramatic increases in speed of computations for an explicit finite element scheme when the GPU was leveraged, and in [6] the authors used the GPU to solve heat transfer and elastic wave propagation problems with the finite difference scheme, again in a much more timely fashion than their CPU counterpart codes. In this paper, the methods of Jianfeng et al are extended to run on the GPU.…”
