A delusion is a strongly held belief despite superior evidence to the contrary.
Almost every person who has performed a CFD analysis has experienced delusion to some degree at one time or another. The thrill that CFD creates by enabling us to visualize the invisible tempts us to believe the fluid always behaves exactly as calculated. In reality, a CFD analysis can be fraught with potential errors that can create inaccurate results if not properly considered.
The Honda Motorcycle R&D Center has been using Cradle SC/Tetra CFD software for nearly ten years to perform thermal analyses for key motorcycle engine components and systems. They know that obtaining accurate CFD predictions is dependent on several factors. Some of these factors are software dependent, and some are process dependent. They include ensuring the CFD software can accurately simulate the fluid/thermal phenoma, the model quality is satisfactory, the correct input conditions are specified, and the output results can be post-processed for visualization and comparison to available measured data. Honda chose SC/Tetra CFD software for its accuracy, speed, ease of use, and post-processing capabilities.
