Volumetric Shrinkage at Ejection
case1 case2
The Volumetric shrinkage at ejection result can be used to detect sink marks on the model. Volumetric shrinkage should be uniform across the whole part to reduce warpage. High shrinkage values could indicate sink marks or voids inside the part. Volumetric shrinkage can be controlled by the use of packing profiles.

Fill Time
case1
case2
The fill time result shows the position of the flow front at regular , as the cavity fills. Each color contour represent the parts of the mold Which were being filled at same time. .The fill time is about 5.6 second in the model . No racetrack effect occur. Air trap appear on the last filled area. Do set enough vent over there.
