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 (SPD) linear systems arising from discretizations of second-order elliptic equations is challenging, especially in applicati…
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…
Towards HPC simulations of Billion-cell Reservoirs by Multiscale Mixed Methods
A. Jaramillo, Rafael T. Guiraldello, Stevens Paz +4
A three dimensional parallel implementation of Multiscale Mixed Methods based on non-overlapping domain decomposition techniques is proposed for multi-core computers and its comput…
