CFD software verification and confirmation database platform

Abstract

The invention discloses a CFD software verification and confirmation database platform which comprises a display layer, an application layer, a service support layer and a resource layer. The displaylayer displays information to different users and provides quick entrances of various service functions; the application layer provides various specific functions for the database platform and achieves data transmission with an external system through an integrated interface; the service support layer mainly provides basic functional components or tools and is divided into a server-side componentand a client-side plug-in; the server-side component provides platform transaction processing, a data interface, a data cache, a workflow engine and a report generation and retrieval engine; the client assembly mainly comprises a data modeling tool, a data display tool, a data import tool, a process modeling tool and a data processing analysis tool; and the resource layer provides a software and hardware platform for supporting the database platform to operate. The database platform provides a special database for CFD software verification and confirmation.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a CFD software verification and confirmation database platform. Background technique [0002] With the rapid development of aerospace technology and computer technology, Computational Fluid Dynamics (CFD) software has become the main tool for researching and designing aerospace vehicles. It has also become one of the hot topics in the international and domestic CFD industry discussions. [0003] The verification and confirmation research of CFD software is very different from what is usually called software testing. The fundamental reason is that the reliability of CFD numerical simulation is based on error analysis. The main object of CFD software verification and confirmation is not limited to software. Whether the implementation itself is smooth and whether the expected results can be obtained, and it is necessary to measure and estimate the source, scope and mutual influen...
