The feed module enables designing and optimizing the feeders and feed aids to obtain the desired quality withhigh yield. Casting solidification is simulated and the results are shown as cooling animation, feed metal paths, andshrinkage porosity distribution. The feeder design can be automatically optimized, driven by user constraints. Here,the last solidifying region of the casting or hotspots in casting has been identified as shown in Fig. 7(a). Green colored dot in the Fig.7 (b) indicates the location of the feeder.
