Current Singularities at Quasi-Separatrix Layers and Three-Dimensional Magnetic Nulls
I. J. D. Craig, Frederic Effenberger
The open problem of how singular current structures form in line-tied, three-dimensional magnetic fields is addressed. A Lagrangian magneto-frictional relaxation method is employed…

Current singularities in line-tied three-dimensional magnetic fields
I. J. D. Craig, D. I. Pontin
This paper considers the current distributions that derive from finite amplitude perturbations of line-tied magnetic fields comprising hyperbolic field structures. The initial equi…

Lagrangian relaxation schemes for calculating force-free magnetic fields, and their limitations
D. I. Pontin, G. Hornig, A. L. Wilmot-Smith +1
Force-free magnetic fields are important in many astrophysical settings. Determining the properties of such force-free fields -- especially smoothness and stability properties -- i…
