The Polymer fill region result is generated at the end of a Fill, Overmolding, or compression-type molding process analysis using 3D analysis technology, and shows which elements in the model are filled with polymer melt at intervals as the cavity fills.
Filled elements are shown as green and unfilled elements as transparent.
The Polymer fill region result is able to show where jetting flow has occurred. If the jetting defect has occurred, a region may fill and unfill repeatedly. This effect is not visible in the Fill time result because the Fill time result can show only one time (the first) that a node fills.
Jetting may result in uneven filling and may lead to air traps inside the part. It can also lead to uneven cooling and increased stress in the part.
Play this result as an animation to spot jetting, which will appear as streams of melted material twisting around.
