A computational study of algebraic coarse spaces for two-level overlapping additive Schwarz preconditioners
Filipe A. C. S. Alves, Alexander Heinlein, Hadi Hajibeygi
The two-level overlapping additive Schwarz method offers a robust and scalable preconditioner for various linear systems resulting from elliptic problems. One of the key to these p…

A stabilized mixed finite element scheme for frictional contact mechanics and shear failure analyses in deformable media with crossing fractures
Luyu Wang, Cornelis Vuik, Hadi Hajibeygi
Simulation of frictional contact and shear failure of fractures in fractured media is of paramount important in computational mechanics. In this work, a preconditioned mixed-finite…
