AlgMortar: a fully algebraic multiscale mortar preconditioner
Luan F. Santos, Fabricio S. Sousa, Roberto F. Ausas +2
The solution of large-scale symmetric positive definite linear systems arising from discretizations of second-order elliptic equations is challenging, especially in applications wi…
Accelerating GMRES with Matrix-Free Multiscale Robin Preconditioners
Dilong Zhou, Rafael T. Guiraldello, Felipe Pereira +1
We propose a matrix-free right-preconditioning strategy for the Generalized Minimal Residual (GMRES) method based on the Multiscale Robin Coupled Method with oversampling (MRCM-OS)…
Fast Converging Parallel Offline-Online Iterative Multiscale Mixed Methods
Dilong Zhou, Rafael T. Guiraldello, Felipe Pereira
In this work, we build upon the recently introduced Multiscale Robin Coupled Method with Oversampling and Smoothing (MRCM-OS) to develop two highly efficient iterative multiscale m…
Multiscale Mixed Methods with Improved Accuracy: The Role of Oversampling and Smoothing
Dilong Zhou, Rafael Guiraldello, Felipe Pereira
Multiscale mixed methods based on non-overlapping domain decompositions can efficiently handle the solution of significant subsurface flow problems in very heterogeneous formations…
Recursive formulation and parallel implementation of multiscale mixed methods
E. Abreu, P. Ferraz, A. M. Espírito Santo +3
Multiscale methods for second order elliptic equations based on non-overlapping domain decomposition schemes have great potential to take advantage of multi-core, state-of-the-art…
