Comment on arXiv:2106.08363v3 [math.NA], E. Abreu, A. Espirito Santo, W. Lambert, and J. Perez, Convergence of a Lagrangian--Eulerian scheme by a weak asymptotic analysis for one-dimensional hyperbolic problems
Frederico Furtado, Felipe Pereira, Li-Ming Yeh
This Comment concerns arXiv:2106.08363v3 [math.NA] by E. Abreu, A. Espirito Santo, W. Lambert and J. Perez, published in Numer. Methods Partial Differential Equations 39 (2023) 240…
Multiscale Sampling for the Inverse Modeling of Partial Differential Equations
Alsadig Ali, Abdullah Al-Mamun, Felipe Pereira +1
We are concerned with a novel Bayesian statistical framework for the characterization of natural subsurface formations, a very challenging task. Because of the large dimension of t…
Conditioning by Projection for the Sampling from Prior Gaussian Distributions
Alsadig Ali, Abdullah Al-Mamun, Felipe Pereira +1
In this work we are interested in the (ill-posed) inverse problem for absolute permeability characterization that arises in predictive modeling of porous media flows. We consider a…
A multiscale Robin-coupled implicit method for two-phase flows in high-contrast formations
Franciane F. Rocha, Fabricio S. Sousa, Roberto F. Ausas +2
In the presence of strong heterogeneities, it is well known that the use of explicit schemes for the transport of species in a porous medium suffers from severe restrictions on the…
The Multiscale Perturbation Method for Two-Phase Reservoir Flow Problems
Franciane F. Rocha, Het Mankad, Fabricio S. Sousa +1
In this work we formulate and test a new procedure, the Multiscale Perturbation Method for Two-Phase Flows (MPM-2P), for the fast, accurate and naturally parallelizable numerical s…
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…
Interface spaces based on physics for multiscale mixed methods applied to flows in fractured-like porous media
Franciane F. Rocha, Fabricio S. Sousa, Roberto F. Ausas +2
It is well known that domain-decomposition-based multiscale mixed methods rely on interface spaces, defined on the skeleton of the decomposition, to connect the solution among the…
Can a falling ball lose speed?
Paulo Murilo Castro de Oliveira, Suzana Moss de Oliveira, Felipe Augusto Pereira +1
A small and light polystyrene ball is released without initial speed from a certain height above the floor. Then, it falls on air. The main responsible for the friction force again…
A New two-dimensional Second Order Non-oscillatory Central Scheme Applied to multiphase flows in heterogeneous porous media
F. Furtado, F. Pereira, S. Ribeiro
We compare the Kurganov-Tadmor (KT) two-dimensional second order semi-discrete central scheme in dimension by dimension formulation with a new two-dimensional approach introduced h…
Central Schemes for Porous Media Flows
E. Abreu, F. Pereira, S. Ribeiro
We are concerned with central differencing schemes for solving scalar hyperbolic conservation laws arising in the simulation of multiphase flows in heterogeneous porous media. We c…
