Polymer fill region result (3D)

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.

Note: For compression-type molding processes, this result is plotted displayed on the deformed mesh as the default setting. With this default setting, if you click through the time steps you can watch the polymer as it is compressed into the part shape. To turn it off, so that all you see is the result on the part, right-click the result, select Properties and uncheck Display on deformed mesh.

Using this result

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.

Things to look for

Play this result as an animation to spot jetting, which will appear as streams of melted material twisting around.

Tip: Use the Cutting Plane tool to see an obscured jet more clearly.
