Thermal Enclosure v1.0.0

Estimate steady-state thermal behaviour of a rectangular enclosure (server rack, electronics housing, equipment cabinet) using a lumped-parameter energy balance with natural-convection and radiation correlations, or forced-flow air energy balance. Accepts enclosure dimensions, heat source positions and wattages, and airflow configuration. Returns temperature extremes, estimated hotspot location, airflow velocity summary, and overall thermal resistance. Runs instantly in-worker; a full CFD container backend is planned for mesh-level detail.

Enclosure length (X) in metres
Enclosure width (Y) in metres
Enclosure height (Z) in metres
Heat sources inside the enclosure
Airflow type
Inlet air velocity in m/s (required for forced flow)
