Complex Multiphysics Simulation Modules#

Simulation modules that combine thermal, mechanical, optical, or electromagnetic models. They are powerful but deeply assumption‑dependent.

Dimensional Core (SET)#

• Spin: depends on domain
• Elec: digital computation
• Temp: often a major axis

Why Red‑Zone#

Multiphysics simulations operate in a high‑fragility inference regime.
Small parameter changes or model mismatches can produce drastically different outputs.

Regime Notes#

• pos‑regime: well‑characterized systems
• Q‑regime: partial coupling, uncertain parameters
• neg‑regime: chaotic or nonlinear interactions

Containment Notes#

Requires explicit model‑scope and parameter‑validity boundaries.
