提出了一种负载平衡启发式并行自适应有限元法（FEM）仿真方法。与大多数现有方法相比，启发式方法侧重于良好的划分形状，而不是最小化经典的边缘切割度量。通过应用代数多重网格（AMG），我们能够在保持大量自然并行性的同时加快该方法中两个最耗时的计算
We propose a load balancing heuristic for parallel adaptive finite element method (FEM) simulations. In contrast to most existing approaches, the heuristic focuses on good partition shapes rather than on minimizing the classical edge-cut metric. By applying algebraic multigrid (AMG), we are able to speed up the two most time consuming calculations of the approach while maintaining its large amount of natural parallelism
