A thermal transient response simulation is performed to determine a total thermal resistance value for a structure having a plurality of thermal model elements. A plurality of thermal transient response simulations are also performed for the structure to determine changed total thermal resistance values by varying one of thermal resistance values of the thermal model elements. Thermal resistance values for the thermal model elements are then determined based on the total thermal resistance value and the changed total thermal resistance values. The structure function is divided into portions associated with the thermal model elements based on the thermal resistance values for the thermal model elements.

Determination of structure function feature correlation to thermal model element layers

A thermal transient response simulation is performed for a structure having a plurality of thermal model elements. The thermal transient response simulation determines a relation between transient thermal impedance of the structure and time and a relation between maximum temperature change of each of the thermal model elements and time. An onset time at which energy reaches each of the thermal model elements is determined based on the relation between maximum temperature change of each of the thermal model elements and time and a predetermined maximum temperature change threshold. An influence onset resistance value for each of the thermal model elements is determined by looking up a thermal resistance value corresponding to the onset time based on the relation between transient thermal impedance of the structure and time. A structural function is mapped based on the influence onset resistance value for each of the thermal model elements.
