Adom Fields: where the current and the heat go on your board.
Board convection h is fixed at 10/25 W/m2K: no spec key for a higher forced-air h
Version: adom-fields 0.10.8
Problem: the board's convection coefficient is fixed in code. H_STILL = 10 W/m²K and H_MOVING = 25 W/m²K are constants in src/fields.rs. fanLevels clamps s to [0, 1], so no spec can solve the board at a forced-air h above 25 W/m²K.
Why it matters: a question like "what airflow does this board need for every hot part to stay inside its rise budget" cannot be answered with a solve once the answer is above 25 W/m²K. On a 98 x 98 mm, 17.4 W power board (AI Flow run biped-pdb), the answer is about 75 W/m²K. I had to fit T = a + b/h per part over the solved levels (h 10, 14, 18, 22, 25; fit residual under 0.6 °C) and extrapolate, with no solve to confirm the result.
Suggestion: optional spec keys hStillWM2k and hMovingWM2k for the board faces (solid bodies already have them), or allow fanLevels above 1. Then airStates can bracket the needed h directly.
