A device includes one or more processors configured to generate simulation data by providing first sets of first values of first input parameters to a simulation of a physical system. The processors are configured to develop at least one surrogate model based on the simulation data, and to select second input parameters from the first input parameters based on the at least one surrogate model. A count of the second input parameters is less than a count of the first input parameters. The processors are configured to generate second simulation data by providing second sets of second values of the second input parameters to the simulation. The processors are configured to develop at least a second surrogate model based on the second simulation data.

Physical system simulation

A computer-based method for evaluating progressive damage in a metal test component includes providing Computed Tomography (CT) image data of the component to a processor and processing the CT image data via the processor, including detecting observable defects in the component. The method also includes characterizing the observable defects into corresponding defect categories, generating a data table of the observable defects and the corresponding defect categories, and embedding a collective set of data from the data table into a finite element model (FEM) of the component to thereby construct a modified FEM of the metal test component. Additionally, the method includes analyzing the modified FEM through an isotropic and/or anisotropic structural model, via the processor, to thereby generate a set of test results. A quality control action is then executed with respect to the metal test component based on the test results.
