Physics reference

Each public physics page follows the same chain:

physical problem → continuous equations → FDM and FEM interpretations → implementation → test → reproducible example.

• Physical conventions and units
• Geometry, regions, materials and meshes
  • Physical model
  • API and ProblemIR impact
  • Validation strategy
  • Known limits and deferred work
• Exchange, demagnetization and Zeeman terms
  • Exchange
  • Demagnetization
  • Zeeman and prescribed fields
  • API and ProblemIR impact
  • Validation strategy
  • Known limits and deferred work

Publication rule

A public physics page must state equations, symbols, SI units, assumptions, backend interpretations, API and ProblemIR impact, validation strategy, known limits and deferred work. Source code or a synthetic oracle alone is not enough to call a backend qualified.
