Posterior exploration for computationally intensive forward models
Mikkel B. Lykkegaard, Colin Fox, Dave Higdon +2
In this chapter, we address the challenge of exploring the posterior distributions of Bayesian inverse problems with computationally intensive forward models. We consider various m…
xSDK Foundations: Toward an Extreme-scale Scientific Software Development Kit
Roscoe Bartlett, Irina Demeshko, Todd Gamblin +12
Extreme-scale computational science increasingly demands multiscale and multiphysics formulations. Combining software developed by independent groups is imperative: no single team…
Algebraic Multigrid Preconditioners for Multiphase Flow in Porous Media
Quan M. Bui, Howard C. Elman, J. D. Moulton
Multiphase flow is a critical process in a wide range of applications, including carbon sequestration, contaminant remediation, and groundwater management. Typically, this process…
On the velocity space discretization for the Vlasov-Poisson system: comparison between Hermite spectral and Particle-in-Cell methods. Part 2: fully-implicit scheme
E. Camporeale, G. L. Delzanno, B. K. Bergen +1
We describe a spectral method for the numerical solution of the Vlasov-Poisson system where the velocity space is decomposed by means of an Hermite basis, and the configuration spa…
On the velocity space discretization for the Vlasov-Poisson system: comparison between Hermite spectral and Particle-in-Cell methods. Part 1: semi-implicit scheme
Enrico Camporeale, Gian Luca Delzanno, Benjamin K. Bergen +1
We discuss a spectral method for the numerical solution of the Vlasov-Poisson system where the velocity space is decomposed by means of an Hermite basis. We describe a semi-implici…
A hybrid HDMR for mixed multiscale finite element method with application for flows in random porous media
Lijian Jiang, J. David Moulton, Jia Wei
Stochastic modeling has become a popular approach to quantify uncertainty in flows through heterogeneous porous media. The uncertainty in heterogeneous structure properties is ofte…
Expanded mixed multiscale finite element methods and their applications for flows in porous media
Lijian Jiang, Dylan Copeland, J. David Moulton
We develop a family of expanded mixed Multiscale Finite Element Methods (MsFEMs) and their hybridizations for second-order elliptic equations. This formulation expands the standard…
