Claim 14:
15. The computer readable medium of claim 13, the instructions further causing the processor to:
determine performance data for the characteristic as a function depending on the at least one variable of the physical model;
extract global parameter values for the at least one parameter based on the performance data using the physical expression;
extract local parameter values for the selected parameter, while keeping fixed the extracted global parameter values for any remaining parameters of the plurality of parameters, based on the performance data corresponding to the characteristic using the physical expression; and
train the ANN function from the extracted local parameter values for the selected parameter,
wherein the hybrid model is defined by a modified physical expression for the characteristic, and
wherein the modified physical expression comprises the same physical nonlinear function depending on the at least one variable, any remaining parameters, and the trained ANN function depending on the at least one variable in place of the selected parameter.
