Abstract

The invention discloses a CCFD (China Computational Fluid Dynamics) system based on an OSGi (Open Service Gateway Initiative) technology. The CCFD system comprises a plug-in engine, a system application plug-in and a component manager, wherein the plug-in engine is responsible for installing and uninstalling the system application plug-in and verifying a dependency relationship; the inner part of the system application plug-in is realized by a component, and service is provided and used by the component; the service issued by the component can be found by analyzing a configuration file of the component, and the service provided by the assembly can be injected into another component applying for the service. Through the technical scheme of the invention, non-intrusive type grey box expansion on the CCFD system can be realized.

Description

technical field [0001] The invention relates to the field of fluid mechanics calculation, in particular to a CCFD system based on OSGi technology. Background technique [0002] Computational fluid dynamics (CFD) technology has been widely used in various fluid engineering fields, such as aviation, aerospace, shipbuilding, power, water conservancy, etc. field expansion. At present, the CFD products used in the field of domestic aircraft design are mainly foreign commercial software. These softwares have shortcomings such as limited precision and limited parallel scale. [0003] The 10,000-core aircraft aerodynamic analysis application software (China Computational fluid dynamics, referred to as CCFD) with independent intellectual property rights in China is an important project under the National 863 Program. The 10,000-core aircraft aerodynamic analysis application software needs to seamlessly integrate the functional modules realized at each stage step by step, and it ca...
