The Gyroid TPMS is an infinitely connected periodic minimal surface belonging to space group $I4_132$. It satisfies the level-set formulation:
For thermal dissipation wafers (such as Therm-Alchemy™ phonon dissipation arrays), sheet gyroids maximize surface area per unit volume while maintaining laminar coolant flow without dead zones.
Wrapping dual-plane planar schematics onto a torus with major radius $R$ and minor radius $r$ requires an orientation-preserving frame field. Standard Frenet-Serret frames introduce catastrophic artificial twists at points of vanishing inflection.
Our engine implements the Rotation-Minimizing Frame (Bishop / Parallel Transport) using the Double Reflection Method. The ribbon cross-section is transported along the toroidal winding curve $u(t) = q \cdot t, v(t) = p \cdot t$, ensuring that the conductor tape experiences strictly minimal torsional strain.
High-temperature superconducting (HTS) REBCO tapes on Hastelloy substrates exhibit critical strain thresholds $\epsilon_{crit} \approx 0.45\%$. For tape thickness $t$ bent to radius of curvature $\rho(t) = 1/\kappa(t)$:
If peak bending strain exceeds $\epsilon_{crit}$, the live strain panel flags the state with a critical red warning, preventing catastrophic mechanical tape fracture during winding.
Every parametric state is hashed via client-side SHA-256 into a 64-character digest representing the immutable mathematical state. Exported CAD files carry this canonical stamp in their standard metadata headers, establishing unbreakable zero-custody digital provenance.
