Fully-implicit Particle-in-Cell model of a Magnetic Nozzle with electromagnetic power deposition
Mario Merino, Juan Martín-Hernández, Pedro Jiménez-Jiménez +1
A fraction of the electromagnetic power used to generate and heat the plasma in helicon sources and electrodeless plasma thrusters can leak into the outer expansion region, interac…
Implementation and Verification of Toroidal Resistive Wall Boundary Conditions in the PIXIE3D MHD code using a Boundary Integral Method
Samuel Jones, Luis Chacón, Jason Hamilton +2
We present the complete formulation of resistive wall boundary conditions in axisymmetric toroidal geometries as implemented in the PIXIE3D extended magnetohydrodynamics (MHD) code…
Comment on "Impact of particle number and cell-size in fully implicit charge- and energy-conserving particle-in-cell schemes" by N. Savard et al., Phys. Plasmas 32, 073903 (2025)
Luis Chacon, Guangye Chen, Lee Ricketson
We take issue with the conclusions in the recent publication by Savard et al. In the study, the authors implement a fully nonlinear charge- and energy-conserving implicit particle-…
A robust fourth-order finite-difference discretization for the strongly anisotropic transport equation in magnetized plasmas
L. Chacon, Jason Hamilton, Natalia Krasheninnikova
We propose a second-order temporally implicit, fourth-order-accurate spatial discretization scheme for the strongly anisotropic heat transport equation characteristic of hot, fusio…
A scalable multidimensional fully implicit solver for Hall magnetohydrodynamics
Luis Chacon
We propose an optimally performant fully implicit algorithm for the Hall magnetohydrodynamics (HMHD) equations based on multigrid-preconditioned Jacobian-free Newton-Krylov methods…
