LIVVkit 2.1: Automated and extensible ice sheet model validation

Evans, Katherine J. (author), Kennedy, Joseph H. (author), Lu, Dan (author), Forrester, Mary M. (author), Price, Stephen (author), Fyke, Jeremy (author), Bennett, Andrew R. (author), Hoffman, Matthew J. (author), Tezaur, Irina (author), Zender, Charles S. (author), Vizcaino, M. (author)

A collection of scientific analyses, metrics, and visualizations for robust validation of ice sheet models is presented using the Land Ice Verification and Validation toolkit (LIVVkit), version 2.1, and the LIVVkit Extensions repository (LEX), version 0.1. This software collection targets stand-alone ice sheet or coupled Earth system models,...

Description and evaluation of the Community Ice Sheet Model (CISM) v2.1

Lipscomb, William H. (author), Price, Stephen F. (author), Hoffman, Matthew J. (author), Leguy, Gunter R. (author), Bennett, Andrew R. (author), Bradley, S.L. (author), Evans, Katherine J. (author), Fyke, Jeremy G. (author), Kennedy, Joseph H. (author)

We describe and evaluate version 2.1 of the Community Ice Sheet Model (CISM). CISM is a parallel, 3-D thermomechanical model, written mainly in Fortran, that solves equations for the momentum balance and the thickness and temperature evolution of ice sheets. CISM's velocity solver incorporates a hierarchy of Stokes flow approximations, including...

Nonlinear dynamics in a magnetic Josephson junction

Hoffman, S. (author), Blanter, Y.M. (author), Tserkovnyak, Y. (author)

We theoretically consider a Josephson junction formed by a ferromagnetic spacer with a strong spin-orbit interaction or a magnetic spin valve, i.e., a bilayer with one static and one free layer. Electron spin transport facilitates a nonlinear dynamical coupling between the magnetic moment and charge current, which consists of normal and...

Once more, into the soup

Stappers, P.J. (author), Hoffman, R.R. (author)

In one of the earlier essays in this department, we discussed a number of acronyms all having to do with system design, and all having the form "x-centered design." The purpose of that essay was to demonstrate a broad framework within which to understand human-centered computing (HCC), and also to show the various convergences and divergences of...

Simulating Drag Crisis for a Sphere Using Skin Friction Boundary Conditions

Hoffman, J. (author)

In this paper we use a General Galerkin (G2) method to simulate drag crisis for a sphere, where the unresolved turbulent boundary layer is modeled as a decreasing skin friction.
