The original question asks about the differences between transient analysis (Ct F P Ct W) and process simulation (F/P/Ct/W).

1. Explanation from Cindy:

Yian-Shin explains that process simulation (F/P/Ct/W) is a fully coupled analysis where temperature data is exchanged synchronously between solvers (Fill, Pack, Cool, and Warp). In contrast, transient analysis (Ct F P Ct W) is decoupled, meaning each solver runs independently, and data is exchanged between solvers through intermediate files.

2. Explanation from Abhash:

Abhash highlights the significance of the first Cool (Ct) stage in transient analysis (Ct F P Ct W). He explains that whether or not you run the first Cool (Ct) step can affect the transient analysis.

3. Question from Andre:

Andre discusses the FillPack Mode:

• • FillPack Mode = 1 (default): This mode calculates the Fill and Pack stages sequentially.

• • FillPack Mode = 2: This mode calculates Fill and Pack stages continuously. The key difference lies in whether intermediate data is exchanged through files or directly passed for continuous calculation.

Mode = 2 is designed for processes without a clear V-P switch, such as Compression Molding or Injection Compression Molding.

Important Note: The FillPack Mode parameter only affects transient analysis (Ct F P Ct W). In process simulation (F/P/Ct/W), Fill and Pack stages are always calculated continuously, so this parameter has no effect.
