This package provides test particle tracing in an analytic or numerical electromagnetic field via DifferentialEquations.jl.
In the Julia REPL,
julia> ]
pkg> add TestParticleVisualization via Makie, Plots, and PyPlot are supported. Please refer to each visualization library's documentation for installations.
TestParticle.jl is designed to work together with OrdinaryDiffEq.jl.
A proton trajectory in a static magnetic field can be traced via
using TestParticle, OrdinaryDiffEq, StaticArrays
# Magnetic field
B(x) = SA[0, 0, 1e-8]
# Electric field
E(x) = SA[0, 0, 0]
# Initial conditions
x0 = [1.0, 0.0, 0.0]
v0 = [0.0, 1.0, 0.1]
stateinit = [x0..., v0...]
tspan = (0, 20)
# Assemble particle + fields
param = prepare(E, B, species=Proton)
prob = ODEProblem(trace!, stateinit, tspan, param)
# Trace trajectory and save positions & velocities
sol = solve(prob, Tsit5(); save_idxs=[1,2,3,4,5,6])For plotting with Makie,
using GLMakie
plot(sol)More tutorials and examples can be found in the doc.
