A new problem solving strategy for complex CFD systems is described, revolving around a new hybrid system which incorporates the advantages of both conventional and expert systems. The paper describes the structure of expert systems and subsequently their operation and illustrates the technique through a local compressible flow analysis example. Comparison of the operations for forward-and backward-chaining expert systems with conventional systems leads to an understanding of the advantages and disadvantages of each. Based upon these observations, a new hybrid system and associated problem solving strategy is described. Application has been made to complex grid adaptation of the two-dimensional Euler equations, highlighting the high efficiency and flexibility of the hybrid system.
