Orbital mechanics
Teaching-resolution orbital mechanics. The gold overlay is the exact ellipse from (a, e). Conserved quantities are diagnostics of the integrator, not a proof of Newtonian gravity.

Finite-difference / Monte Carlo / RK scheme at teaching resolution. Conserved quantities are diagnostics. FrameCalc is an educational workbench. It is not for medical, nuclear-safety, radiation-protection, or engineering sign-off. Fusion and IEC estimates are models, not device predictions. Accuracy · Legal
