Water Resources Research, Volume 62, Issue 1, January 2026.Abstract Understanding how snowmelt is partitioned into different hydrologic flowpaths/storages—and how this partitioning varies over time—is essential for predicting water availability and quality under climate variability. In this study, we examine the time‐variance of snowmelt partitioning patterns (SPP) in response to interannual variations in ...

Solving the Einstein constraints in periodic spaces with a multigrid approach
, 2013 Novel applications of Numerical Relativity demand for more flexible algorithms and tools. In this paper, I develop and test a multigrid solver, based on the infrastructure provided by the Einstein Toolkit, for elliptic partial differential equations on ...

International Journal of Energy Research, Volume 2026, Issue 1, 2026.The utilization of clean hydrogen energy in eco‐friendly mobility systems has gained increasing attention in the pursuit of carbon neutrality. As demand for hydrogen mobility rapidly grows, it becomes essential to expand and distribute hydrogen charging stations, thereby increasing the need for an efficient hydrogen compression process.

Multigrid Method versus Staging Algorithm for PIMC Simulations
, 1996 We present a comparison of the performance of two non-local update algorithms for path integral Monte Carlo (PIMC) simulations, the multigrid Monte Carlo method and the staging algorithm.

International Journal for Numerical Methods in Engineering, Volume 126, Issue 24, 30 December 2025.ABSTRACT Solid oxide fuel cells (SOFCs) are a promising technology for producing clean energy in the future. To enhance the efficiency and the lifetime of SOFCs and SOFC stacks, novel materials and innovative material compositions for the constituent layers—namely the cathode, anode, and electrolyte—must be developed.

Kinematics of Multigrid Monte Carlo
, 1992 We study the kinematics of multigrid Monte Carlo algorithms by means of acceptance rates for nonlocal Metropolis update proposals. An approximation formula for acceptance rates is derived. We present a comparison of different coarse-to-fine interpolation

Analysis of a parallel multigrid algorithm [PDF]
The parallel multigrid algorithm of Frederickson and McBryan (1987) is considered. This algorithm uses multiple coarse-grid problems (instead of one problem) in the hope of accelerating convergence and is found to have a close relationship to traditional

Adaptive metric-based multigrid for a Poisson problem with discontinuous coefficients*, **
ESAIM: Proceedings and Surveys, 2014 In order to solve the linear partial differential equation Au = f, we combine two methods: Full-Multigrid method and Hessian-based mesh adaptation.

A new wavelet multigrid method for the numerical solution of elliptic type differential equations
Alexandria Engineering Journal, 2018 In this paper, we present a new wavelet multigrid method for the numerical solution of elliptic type differential equations based on Daubechies (db4) high pass and low pass filter coefficients with modified intergrid operators. The proposed method is the
