我们开发了一个能够计算超过10亿个有限元的非线性多尺度解决方案的三维，层次的有限菌株多尺度求解器，在FE2的静脉中，我们使用了1552个计算芯上的5.74亿个非线性方程。将求解器用于异质性超弹性层的多尺度凝聚力建模。矩阵通过在不同尺度上覆盖计算来限制潜伏期，饥饿和开销。空间分辨率。
We develop a three‐dimensional, hierarchically parallel, finite strain multiscale solver capable of computing nonlinear multiscale solutions with over 1 billion finite elements and over 574 million nonlinear equations on 1552 computing cores. In the vein of FE2, we use the nested iterative procedure and devote the solver to multiscale cohesive modeling of heterogeneous hyperelastic layers. The hierarchically parallel multiscale solver takes advantage of a client‐server non‐blocking communication matrix that limits latency, starvation, and overhead by overlaying computations at different scales. We perform simulations of real‐scale engineering devices and bridge O(106) in length‐scales, spanning from O(101) mm to O(101) nm in spatial resolution. Verification of the hierarchically parallel solver is provided together with a mesh convergence study. Moreover, we report on the scaling performance. Copyright © 2014 John Wiley & Sons, Ltd.
