The Barnes-Hut tree: how a quadtree approximates distant charges.
Boltzmann electrons on the quadtree: the tree leaves as the quadrature of a nonlinear source.
Conductors at prescribed potentials, by the boundary-integral (panel) method.
Charge-exchange ions in an ion-thruster grid set: where they land and what they erode.
Space-charge-limited emission in a gridless code: the planar Child-Langmuir diode.
A tree code that conserves both momentum and energy: the evidence, as figures.
Parameter studies behind the conserving tree code, as figures.
An ion-mobility drift tube: drift velocity, diffusion and resolving power.
A slit (2D) einzel lens: both polarities focus, the decelerating one much more strongly.
The fast multipole method: O(N) fields of line charges.
An implicit, exactly energy-conserving push for N-body plasma: what it costs.
Ion extraction through an aperture, by the tree code plus boundary-integral electrodes.
Two-surface multipactor between parallel plates, with surface impacts from simgeometry.
A planar Pierce electron gun: a space-charge-limited sheet beam kept parallel.
A plasma sheath between two grounded (Dirichlet) walls.
Rational far fields: equivalent charges with free poles against the multipole series.
A gridless reflectron time-of-flight mass spectrometer, and its energy focusing.
Steady-state space-charge optics without a mesh: trajectories as line charges.
