Casting process modeling technology has come a long way since the early and mid-1980s, when the design engineer worked with just a 2-D model. The early days focused on the simple quest of identifying hot spots in the casting. As the CAD and numerical simulation software packages evolved, quick changes to the design of the casting could be made with relative ease. Most of the casting simulation packages today can handle solidification and fluid flow in the mold with relative ease, and the role of such tools continues to grow, both in the design of the component and optimization of the casting process to produce a functional part under intended loading. The advancement in computer hardware available to run these programs with multiple CPU configurations allows a fast turnaround time by increasing the speed of solution, even on large models.
