Accurate definition of local heat transfer coefficients, as a function of temperature, is required to properly model transient thermal processes. DEFORM provides an optimization-based Inverse Heat Transfer Coefficient (HTC) Module that extracts heat transfer coefficients from experimental thermocouple data. This easy-to-use module guides the user through data preparation and post-processing. Modeling results include a set of heat transfer coefficients and temperature validation plots.

Time vs. temperature is shown for two locations when quenching a nickel alloy disk. The mismatch between predicted and actual temperature is the result of using a constant heat transfer coefficient, that does not match reality.
These heat transfer coefficients are compared to the final values, which are a function of temperature and location. DEFORM uses optimization techniques to accurately match the experimental data.
The final simulation, using updated HTC values, accurately matches the experimental data.
