Problem

WeberProblem(system, tspan, q_initial, p_initial; kwargs...)

Fully specified n-body Weber electrodynamics problem ready for integration.

Packages the compiled WeberSystem, initial conditions, physical parameters, and solver/regularization options into a single immutable structure.

Arguments

• system::WeberSystem: Pre-built symbolic + compiled Hamiltonian system.
• tspan::Tuple{Real,Real}: Integration interval (t_start, t_end).
• q_initial::AbstractVector: Flattened initial positions, length = n_particles × dims.
• p_initial::AbstractVector: Flattened initial momenta, length = n_particles × dims.

Keywords

• masses: Particle masses (all positive), length n_particles.
• charges: Particle charges, length n_particles.
• c: Speed of light (positive).
• dt: Fixed macro time step (positive).
• convergence_tolerance=1e-13: Fixed-point convergence threshold for projection.
• maximum_iterations=100: Maximum projection iterations per step.
• regularization=RegularizationOptions(): Close-encounter regularization options. See RegularizationOptions for all available fields.
• zollner=ZollnerOptions(): Zöllner electrogravitational extension options. See ZollnerOptions for all available fields.
