Physical conventions and units

Last changes: Documentation changelog

FullMag uses SI units unless a page explicitly states otherwise. Every interaction page defines symbols, signs, coordinate orientation, magnetization normalization and assumptions.

Symbol

Meaning

SI unit

m

normalized magnetization

dimensionless

M

magnetization

A/m

M_s

saturation magnetization

A/m

H

magnetic field

A/m

B

magnetic flux density

T

A

exchange stiffness

J/m

t

time

s

f

frequency

Hz

alpha

Gilbert damping parameter

dimensionless

The project-wide convention is maintained in docs/physics/llg_conventions.md and docs/physics/0000-physics-documentation-standard.md. Public pages may summarize it, but may not introduce a second sign or unit convention.

Control Room crosswalk

Use Model Explorer -> Objects -> <object> -> Geometry or Material as named by the linked API page. Status: partial. 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

  • Public Python and lowering sources are linked by the applicable terminal API page. Runtime realization is in the relevant backends/fdm or backends/fem lane; frontend ownership is apps/control-room/src/modules/inspector/panels/PhysicsInteractionPanel.tsx where a live control exists.
