A technique is described for taking results from complex numerical modelling procedures (such as a finite element model, a dynamic simulation or from experimental data) to create a simple yet accurate mathematical description of a device based on a modest amount of input data. The analytic model is then available for use within design or control programs that need to evaluate many examples quickly. The technique may be applied to a wide range of devices or systems. Examples are given for three applications.
