ERF: Energy Research and Forecasting Model

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 11, November 2025.
Abstract High performance computing (HPC) architectures have undergone rapid development in recent years. As a result, established software suites face an ever increasing challenge to remain performant on and portable across modern systems. Many of the widely adopted atmospheric modeling codes cannot fully (or in some cases, at all) leverage the ...

Generalized Multiscale Finite Element Method for Elastic Wave Propagation in the Frequency Domain

Computation, 2020
In this work, we consider elastic wave propagation in fractured media. The mathematical model is described by the Helmholtz problem related to wave propagation with specific interface conditions (Linear Slip Model, LSM) on the fracture in the frequency ...

Quantifying the Influence of Fault Geometry via Mesh Morphing With Applications to Earthquake Dynamic Rupture and Thermal Models of Subduction

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract Subsurface geometries, such as faults and subducting slab interfaces, are often poorly constrained, yet they exert first‐order control on key geophysical processes, including subduction zone thermal structure and earthquake rupture dynamics.

A Filter‐Matrix Lattice‐Boltzmann Methodology for Convective Melting and Solidification

International Journal for Numerical Methods in Fluids, Volume 97, Issue 10, Page 1379-1393, October 2025.
We propose a new methodology for simulating melting and solidification that can be used in lattice‐Boltzmann schemes that are based on filter‐matrix collision operators. The methodology includes an iteration‐free source‐based enthalpy method for phase‐change and an immersed boundary technique.

3D Dynamic Rupture Modeling of the 2021 Haiti Earthquake Used to Constrain Stress Conditions and Fault System Complexity

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract The 2021 Mw ${M}_{w}$7.2 Haiti earthquake was a devastating event which occurred within the Enriquillo Plantain Garden Fault Zone (EPGFZ). It is not well‐understood why neither the 2021 nor the prior 2010 Mw ${M}_{w}$7.0 earthquakes were pure strike slip events and, instead, ruptured with distinct patches of dip slip and strike slip motion on ...

Large Eddy Simulation of Canonical Atmospheric Boundary Layer Flows With the Spectral Element Method in Nek5000

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 10, October 2025.
Abstract Simulation of turbulence in the atmospheric boundary layer (ABL) is challenging due to the wide range of turbulent scales in the flow. To leverage the currently available computational power for high‐resolution simulation of atmospheric turbulence, fluid solvers that scale well on large compute clusters are required.

Can Second‐Order Numerical Accuracy Be Achieved for Moist Atmospheric Dynamics With Non‐Smoothness at Cloud Edge?

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 10, October 2025.
Abstract Non‐smoothness arises at cloud edge because, in moist thermodynamics, the thermodynamic properties of the atmosphere are different inside a cloud versus in clear air. In particular, inside a cloud, the vapor pressure of water is constrained by the saturation vapor pressure, which acts as a threshold.
