Geometric multigrid methods for Darcy–Forchheimer flow in fractured porous media
Arrarás Ventura, Andrés
; Gaspar, F. J.; Portero Egea, Laura ; Rodrigo, C. (Elsevier, 2019)
Artículo / Artikulua 
In this paper, we present a monolithic multigrid method for the efficient solution of flow problems in fractured porous media. Specifically, we consider a mixed-dimensional model which couples Darcy flow in the porous ... -
Mixed-dimensional geometric multigrid methods for single-phase flow in fractured porous media
Arrarás Ventura, Andrés ; Gaspar, F. J.; Portero Egea, Laura ; Rodrigo, C. (SIAM, 2019)
Artículo / Artikulua
This paper deals with the efficient numerical solution of single-phase flow problems in fractured porous media. A monolithic multigrid method is proposed for solving two-dimensional arbitrary fracture networks with vertical ... -
Multigrid solvers for multipoint flux approximations of the Darcy problem on rough quadrilateral grids
Arrarás Ventura, Andrés ; Gaspar, F. J.; Portero Egea, Laura ; Rodrigo, C. (Springer, 2020)
Artículo / Artikulua
In this work, an efficient blackbox-type multigrid method is proposed for solving multipoint flux approximations of the Darcy problem on logically rectangular grids. The approach is based on a cell-centered multigrid ... -
Multipoint flux mixed finite element methods for slightly compressible flow in porous media
Arrarás Ventura, Andrés ; Portero Egea, Laura (Elsevier, 2019)
Artículo / Artikulua
In this paper, we consider multipoint flux mixed finite element discretizations for slightly compressible Darcy flow in porous media. The methods are formulated on general meshes composed of triangles, quadrilaterals, ... -
Space-time parallel methods for evolutionary reaction-diffusion problems
Arrarás Ventura, Andrés ; Gaspar, F. J.; Portero Egea, Laura ; Rodrigo, C. (Springer, 2023)
Contribución a congreso / Biltzarrerako ekarpena
In recent years, the gradual saturation of parallelization in space has been a strongmotivation for the design and analysis of new parallel-in-time algorithms. Amongthese methods, the parareal algorithm, first introduced ...
