Fill analysis

The Fill analysis predicts the thermoplastic polymer flow inside the mold in the filling phase. This analysis is often run as the first part of a Fill+Pack analysis sequence.

A Fill analysis calculates the flow front that grows through the part incrementally from the injection location, and continues until the velocity/pressure switch-over point has been reached. A Runner Balance analysis can be used with a Fill analysis to ensure equal pressure is delivered at each cavity.

The Fill Analysis accepts eight laminates across the part thickness to calculate results. If symmetrical thermal boundary conditions exist, and Cool Analysis results are not available, the analysis is based on a half-gap calculation and the actual number of laminates used in the calculation is four. This is reflected symmetrically across the part for a total of eight laminates. Running a Cool Analysis prior to running a Fill Analysis provides asymmetrical cooling information, and the full eight laminates are used to calculate results.

Supported analysis technologies

Select the most suitable analysis technology by using the following information:

Dual Domain analysis technology, Fill analysis

This works by simulating the flow of the melt on both the top and bottom surfaces of the mold cavity (surface shell). This analysis is most accurate for thin-walled parts.

3D analysis technology, Fill analysis

This is a high-end flow simulation tool that helps you understand how plastic flows in thick-walled parts, or parts containing thick sections.
