Hierarchical structure analysis in verification and validation of aerodynamic numerical simulation

Abstract

Verification and validation is a basic way to ensure the credibility of numerical simulation. The realization of verification and validation of aerodynamic numerical simulation requires scientific and rigorous processes. At present, long-term research on verification and validation at home and abroad has summarized the whole verification and validation process into four stages: problem analysis, verification, validation and credibility evaluation. In each stage, it is of great significance to use the hierarchical structure to sort out key information and clarify tasks. This paper summarizes the application of hierarchical structure in the verification and validation process, and gives examples of aerodynamic numerical simulation with application value.
