# Casting solidification-time screening
# Scope: Reference-calibrated Chvorinov volume-to-cooling-area scale with exponent two.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

volume = 100 cm^3
area = 200 cm^2
referenceModulus = 5 mm
referenceTime = 60 s

modulus := volume/area [mm]
duration := referenceTime*(modulus/referenceModulus)^2 [s]

check solidification time budget: duration <= 120 s

scenario alternative: volume = 80 cm^3
