Comparison of FETI-based domain decomposition methods for topology optimization problems

Comparison of FETI-based domain decomposition methods for topology optimization problems

We critically assess the performance of several variants of dual and dual-primal domain decomposition strategies in problems with fixed subdomain partitioning and high heterogeneity in stiffness coefficients typically arising in topology optimization of modular structures. Our study considers Total...
