Pack analysis

A Pack analysis predicts the thermoplastic polymer flow inside the mold in the packing phase. This analysis is run as the second part of a Fill+Pack analysis sequence and can be used to determine whether a cavity will be completely filled.

A Pack analysis calculates a flow front that grows from the locations in the model the flow front had filled when the velocity/pressure switch-over point was reached. The analysis continues until the flow front has expanded to fill the last location in the model.

A Pack analysis accepts a minimum of 8 and a maximum of 20 laminates across the part thickness to calculate results. The default number of laminates across the thickness is 12. You can change this value by editing the solver parameters.

If symmetrical thermal boundary conditions exist (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 half of the specified number, reflected symmetrically across the part. Running a Cool analysis prior to running a Fill+Pack analysis provides asymmetrical cooling information, and the full specified number of laminates is used to calculate results.
