Based on expert system theory and fluid–structure interaction (FSI), this paper suggests an intelligent design optimization system to derive the optimal shape of both the fluid and solid domain of flow channels. A parametric modeling scheme of flow channels is developed by design for additive manufacturing (DfAM). By changing design parameters, a series of flow channel models can be obtained. According to the design characteristics, the system can intelligently allocate suitable computational models to compute the flow field of a specific model. The pressure-based normal stress is abstracted from the results and transmitted to the solid region by the fluid–structure (FS) interface to analyze the strength of the structure. The design space is obtained by investigating the simulation results with the metamodeling method, which is further applied for pursuing design objectives under constraints. Finally, the improved design is derived by gradient-based optimization. This system can improve the accuracy of the FSI simulation and the efficiency of the optimization process. The design optimization of a flow channel in a simplified hydraulic manifold is applied as the case study to validate the feasibility of the proposed system.

Ray's most widely read book was his Wisdom of God manifested in the works of creation (1691), probably based on addresses given in the chapel of Trinity College Cambridge 20 years previously. In it he forswore the use of allegory in biblical interpretation, just as he had done in his (and Francis Willughby's) Ornithology (1678). His discipline seeped into theology, complementing the influence of the Reformers and weakening Enlightenment assumptions about teleology, thus softening the hammer-blows of Darwinism on Deism. The physico-theology of the eighteenth century and the popularity of Gilbert White and the like survived the squeezing of natural theology by Paley and the Bridgewater Treatises a century after Wisdom … , and contributed to a peculiarly British understanding of natural theology. This undergirded the subsequent impact of the results of the voyagers and geologists and prepared the way for a modern reading of God's “Book of Works” (“Darwinism … under the disguise of a foe, did the work of a friend”). Natural theology is often assumed to have been completely discredited by Darwin (as well as condemned by Barth and ridiculed by Dawkins). Notwithstanding, and despite the vapours of vitalism (ironically urged – among others – by Ray's biographer, Charles Raven) and the current fashion for “intelligent design”, the attitudes encouraged by Wisdom … still seem to be robust, albeit needing constant re-tuning (as in all understandings influenced by science).
