基于Agent的CFD自主求解系统研究

DESIGN OF AGENT-BASED CFD SOLVER FRAMEWORK

在用Agent概念对复杂软件系统抽象的基础上,强调Agent在CFD求解系统中的自主性和智能性,实现具有推理能力的计算实体。通过基于角色的系统分析和改进的BD I模型Agent构建方法,将求解系统构建为一个多Agent系统。求解过程中由A-gent控制子区域独立计算,根据解的收敛变化情况在不同数值方法间切换,根据子域之间边界点数据的变化实时决定通信的时机。同时介绍了系统的结构和各个Agent的主要工作。

An autonomy agent-based framework of the given fluid field computing system is proposed. The paper describes how the system works in solving the given problem by splitting the solving domain into sub-domain, switching numerical scheme timely and deciding when to appropriately interact the ghost cell values at run time. The improved BDI （Belief-Desire-Intention） model agent architecture is adopted for the rational requirement of the system. In such a system intelligent agents are used to a） control the execution of individual solvers on each subdomain and coordinate the execution of the staff, b） mediate rationality between adjacent sub-domains, and c） switch different numerical scheme during the solution.
