Abstract
A compensation field indicating an amount of distortion compensation to be applied across at least a portion of a component is determined, and a nominal computer-aided design (CAD) model of a component is modified based on the compensation field. The amount of distortion compensation corresponds to a multiplication product of: (i) a deviation between the nominal CAD model and a physical representation of the component having been produced based on the nominal CAD model, and (ii) a nonlinear scale factor map that includes a map associating a plurality of locations of the nominal CAD model to corresponding ones of a plurality of scale factors respectively representing an increase or a decrease in the amount of distortion compensation to be applied based on a simulated effect upon the component in response to an iterative simulation process.
