Overview of Recent NIMROD-Based Computational Work at the Univ. of Wisconsin-Madison

POSTER

Abstract

The NIMROD code (https://nimrodteam.org) is a versatile and well tested computational tool for modeling macroscopic dynamics in magnetized plasma. The Center for Plasma Theory and Computation at the Univ. of Wisconsin-Madison presently applies NIMROD in studies of magnetic relaxation in reversed-field pinches and spheromaks, non-inductive current drive in spherical tokamaks, vertical-displacement instability, resistive-wall mode, edge localized modes and resonant magnetic perturbation in tokamaks, and magnetic topology evolution in a stellarator-tokamak hybrid. Recent contributions to NIMROD development include spectral-element stabilization, nodal trigonometric basis functions, resistive-wall options, and magnetization effects in viscosity. A summary of this application and development work is presented, along with a perspective on NIMROD modeling.
