Abstract
A method and system for optimizing a simulated casting of a light weight alloy component. The simulation includes passing component design data through various computational modules relating to casting designs, process modeling and optimization, material microstructure and defects and product performance. Variations in microstructure and defects across various very small size scales are extended to increasingly larger scales to permit structural performance calculations of the cast component to take such non-uniformities into consideration. At least some of the modules employ an expert system-based approach to achieve the optimized results. The results can be compared to end user needs to determine if redesign of the part geometry or manufacturing process is needed.
