Black box/white box hybrid method for virtual prototyping validation of multiphysics simulations and testing

Abstract

Abstract A hybrid method has been developed to predict the level of confidence in the results of multiphysical behavioural simulations of the object by virtue of virtual prototyping (VP) together with physical PP testing based on the stage of the virtual prototyping process and feedback from physical parameters tests. The method is based on a three approaches to assessing the reliability of the results of virtual prototypes - initial - for verification of boundary conditions, intermediate - to improve the accuracy of the results obtained and final -to validate the obtained results. A new method has been developed to improve the efficiency and effectiveness of Virtual Prototyping called “WHITE BOX / BLACK BOX” for the study of complex objects by applying VP as a “white box” and VP as a “black box” in iterative connectivity to achieve fine calibration of VP. The novelty of the method lies in the iterative connectivity of the VP and the PP, and in particular the calibration of the VP by feedback from PP data via a micro-cycle. The “WHITE BOX / BLACK BOX” method and the three approaches to verifying and validating VP have been demonstrated in three successfully completed projects with international industrial partners used as demonstration test cases.
