Fields

time: f64

Simulation time at this diagnostic snapshot.

total_energy: f64

Total energy E = T + W (kinetic + potential).

kinetic_energy: f64

Kinetic energy T = (1/2) integral f v^2 dx^3 dv^3.

potential_energy: f64

Potential energy W = (1/2) integral rho Phi dx^3.

virial_ratio: f64

Virial ratio 2T/|W|. Equals 1.0 in virial equilibrium.

total_momentum: [f64; 3]

[px, py, pz]: total momentum components.

total_angular_momentum: [f64; 3]

[Lx, Ly, Lz]: total angular momentum components.

casimir_c2: f64

Casimir invariant C2 = integral f^2 dx^3 dv^3.

entropy: f64

Boltzmann entropy S = -integral f ln(f) dx^3 dv^3.

mass_in_box: f64

Total mass in the domain: M = integral f dx^3 dv^3.

casimir_c2_pre_lomac: Option<f64>

Casimir C₂ measured before LoMaC projection (None if LoMaC inactive).

casimir_c2_post_lomac: Option<f64>

Casimir C₂ measured after LoMaC projection (None if LoMaC inactive).

near_field_correction_magnitude: Option<f64>

L2 norm of the near-field correction applied during Poisson solve (None if not applicable).

coarse_grained_entropy: Option<f64>

Coarse-grained entropy S_bar = -Sum f_bar ln(f_bar) dV (None if not computed).

symplecticity_error: Option<f64>

Per-step symplecticity error estimated from Casimir C₂ drift.

For a symplectic integrator the Casimir invariants are exactly conserved (absent truncation). This field stores |ΔC₂/C₂| for the most recent step, or None if no previous step exists yet.
