VSim is a flexible, multiplatform, high-performance tool for running electromagnetic, electrostatic, and plasma simulations in 1, 2, or 3 dimensions.
VSim solves EM propagation in the presence of complex dielectric and metallic shapes with accurate simulation of curved geometries using a conformal mesh. Examples include:
Far Field calculations
Radar Cross Sections
The kinetic plasma model is based on the particle-in-cell (PIC) algorithm, both in the electromagnetic and electrostatic limits. For electromagnetics, a charge-conserving current deposition algorithm enables the integration of the Maxwell equations without any additional divergence correction. In the electrostatic limit, the VSim computational engine (Vorpal) solves Poisson’s equation at every time step based on the instantaneous charge distribution. Examples include:
Multipacting in waveguides
Traveling Wave Tubes
Laser Plasma Accelerators
The structures within the VSim applications can be arbitrarily shaped and can define the locations of conductors, dielectrics, particle absorbers, reflectors, and other geometrical objects.
