Finite spatial-grid effects in energy-conserving particle-in-cell algorithms
D. C. Barnes, L. Chacon
Finite-grid (or aliasing) instabilities are pervasive in particle-in-cell (PIC) plasma simulation algorithms, and force the modeler to resolve the smallest (Debye) length scale in…
A conservative phase-space moving-grid strategy for a 1D-2V Vlasov-Fokker-Planck Equation
William Tsubasa Taitano, Luis Chacon, Andrei Simakov +1
We develop a conservative phase-space grid-adaptivity strategy for the Vlasov-Fokker-Planck equation in a planar geometry. The velocity-space grid is normalized to the thermal spee…
A semi-implicit, energy- and charge-conserving particle-in-cell algorithm for the relativistic Vlasov-Maxwell equations
Guangye Chen, Luis Chacón, Lin Yin +3
Conventional explicit electromagnetic particle-in-cell (PIC) algorithms do not conserve discrete energy exactly. Time-centered fully implicit PIC algorithms can conserve discrete e…
A fully implicit, scalable, conservative nonlinear relativistic Fokker-Planck 0D-2P solver for runaway electron
Don Daniel, William T. Taitano, Luis Chacón
Upon application of a sufficiently strong electric field, electrons break away from thermal equilibrium and approach relativistic speeds. These highly energetic runaway electrons (…
A Multigroup Moment-Accelerated Deterministic Particle Solver for Time-dependent Thermal Radiative Transfer Problems
H. Park, L. Chacon, A. Matsekh +1
We propose an efficient, robust, Lagrangian (characteristic-based) transport solver for the time-dependent thermal radiative Transfer (TRT) applications within the context of a mom…
