Analysis of grid instabilities in particle-in-cell codes based on a meshfree approach
J. M. Finn, E. G. Evstatiev
A new method of analyzing grid, or aliasing, instabilities is described, in particle-in-cell (PIC) codes for plasma kinetic theory. It starts with a meshfree approach with …
Initializing and stabilizing variational multistep algorithms for modeling dynamical systems
C. L. Ellison, J. W. Burby, J. M. Finn +2
Backward error initialization and parasitic mode control are well-suited for use in algorithms that arise from a discrete variational principle on phase-space dynamics. Dynamical s…
Symplectic integrators with adaptive time steps
A S Richardson, J M Finn
In recent decades, there have been many attempts to construct symplectic integrators with variable time steps, with rather disappointing results. In this paper we identify the caus…
Quasi-separatrix layers and three-dimensional reconnection diagnostics for line-tied tearing modes
A. S. Richardson, J. M. Finn
In three-dimensional magnetic configurations for a plasma in which no closed field line or magnetic null exists, no magnetic reconnection can occur, by the strictest definition of…
Regression with strongly correlated data
C. S. Jones, J. M. Finn, N. Hengartner
This paper discusses linear regression of strongly correlated data that arises, for example, in magnetohydrodynamic equilibrium reconstructions. We have proved that, generically, t…
