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.
A Fill 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 analysis provides asymmetrical cooling information, and the full specified number of laminates is used to calculate results.
