Physics foundations

Last changes: Documentation changelog

These pages define the shared physical contract that every FullMag interaction, solver backend, and observable must satisfy. They are not interaction-specific; instead they establish the conventions, equations, and quantities that the interaction pages build upon.

Start with Conventions and units for the SI unit table and solver-field naming, then read Micromagnetic energy for the total energy and variational principle, and Effective field for the field vs. torque distinction. The Landau–Lifshitz–Gilbert equation page defines the equation of motion. Boundary conditions covers the boundary-condition types shared across interactions. Observables documents the output system.

Control Room crosswalk

This is a navigation page; the selected interaction or foundation is configured by its linked Python API and object/stage editor. The category itself has no standalone control. frontend support is not implemented applies to physical parameters without a matching control. See {doc}/frontend/capability-register; do not infer UI support from backend or Python availability.

Python/API crosswalk

The linked Python API page is authoritative for exact functions, arguments, units, and failure semantics. If this page is a foundation or category overview, runnable Python is ot applicable here and must be taken from the terminal API page.

Bibliography and source scope

Use the scientific bibliography and source-code index on the linked terminal page. This block adds no new equation or unverified implementation claim.

Source-code index

This is a navigation page and introduces no standalone implementation symbol. The exact source-code index is maintained by the selected terminal page.
