Abstract: A computer-implemented method of automatically determining an optimized design for manufacturing a real-world object includes: defining, in memory of a computer-based processor, a finite element model representing a real-world object, the finite element comprising a plurality of elements; evaluating, with the computer-based processor, a distribution of a design variable throughout a vicinity of the finite element model, using singular value decomposition (SVD), to produce a singular value for the design variable in each respective element in the vicinity of the finite element model; defining optimization constraints for the vicinity of the finite element model based on the singular values produced from the SVD; and optimizing the finite element model with respect to the design variable by locally enforcing a geometry of the real-world object in the vicinity based on the defined optimization constraints.

Abstract: A computer-implemented method for verifying a model in a product lifecycle management (PLM) system includes defining a model and an envelope of allowable model states and, based on one or more requirements, deriving at least one counterexample objective. The method also includes optimizing a set of parameters related to the allowable model states and the allowable model context, redefining at least one of the model and the allowable model states when the at least one counterexample objective is outside of a specified tolerance, and, after a predefined number of iterations, defining the model as verified.
