Scalability of parallel solvers for problems with high heterogeneities relies on adaptive
coarse spaces built from generalized eigenvalue problems in the subdomains. The …

A GenEO domain decomposition method for saddle point problems

F Nataf, PH Tournier - Comptes …, 2023 - comptes-rendus.academie-sciences …
We introduce an adaptive element-based domain decomposition (DD) method for solving
saddle point problems defined as a block two by two matrix. The algorithm does not require …
