Abstract	Product design is a complex decision-making process requiring intensive interactions between designers and the designed product, especially in cases involving complex geometric shape creation and optimization. Virtual engineering is presented as a next-generation product realization system that integrates product models and engineering tools using virtual reality technology as a platform, which extends the application scope of virtual reality from visualization to interaction and decision making. The interaction between designers and product models is enabled by computing the engineering analysis models, wherein most researchers believe that the conflict between analysis accuracy and speed always exists. In this paper, several solution acceleration methods of high-fidelity computational fluid dynamics models are introduced, e.g., idealization, grid reduction, and a new convergence criterion. We have observed that it is possible to improve analysis accuracy and speed concurrently, and designers must consider specific design requirements when compromising these two factors. To demonstrate this idea, a hydraulic mixing nozzle design and analysis scenario is introduced. It has been shown that when conducting engineering analysis, design requirements are the primary factors that should be considered.
