This simulation illustrates the filling and solidification of ductile cast iron crankshafts, which was used to investigate a directional solidification into the risers. FLOW-3D CAST can be used to predict and avoid casting defects. Accounting for factors in cast iron including carbon expansion, primary (open) shrinkage cavities and secondary (internal) shrinkage cavities can be reliably displayed. Based on the size and position of the defects, the necessity of improvements to the casting design can be determined.
