Matrix-free higher-order finite element methods for hyperelasticity
Computer Methods in Applied Mechanics and Engineering ( IF 6.9 ) Pub Date : 2024-12-06 , DOI: 10.1016/j.cma.2024.117600 R. Schussnig, N. Fehn, P. Munch, M. Kronbichler

This work presents a matrix-free finite element solver for finite-strain elasticity adopting an h p -multigrid preconditioner. Compared to classical algorithms relying on a global sparse matrix, matrix-free solution strategies significantly reduce memory traffic by repeated evaluation of the finite element integrals.

超弹性的无矩阵高阶有限元方法
这项工作提出了一种采用 hp-multigrid 预条件器的无矩阵有限应变弹性有限元求解器。与依赖于全局稀疏矩阵的经典算法相比,无矩阵求解策略通过重复计算有限元积分来显著减少内存流量。
