This means that before the compression switch, the amount of resin injected is calculated as: (Part + Compression) * VP switched volume (i.e., 70%).
Therefore, the difference in resin volume is an influencing factor that causes the variation in warpage. The change in resin quantity affects the pressure, which in turn influences warpage.

Since the 2024 R2 version, the computing manager has only shown performance-cores as the default setting. This is because performance-cores are faster and using other cores might cause some issues.

Basically, if you select all three criteria, we take the intersection of them. In most cases, we only use part weight for calculations. Since the temperature/ flow rate would be hard to measure in reality.

Warpage Results vs. Differential Shrinkage EffectOur warpage solver primarily considers two main effects: differential temperature and differential shrinkage effects.Differential shrinkage effects The differential shrinkage displacement represents the in-plane shrinkage due to PVT distribution. The displacement is calculated based on the average volumetric shrinkage across the thickness of the same cutting plane. Since this effect averages across the thickness, it does not vary in the vertical (thickness) direction.On the other hand, Differential temperature effect displacement is calculated with the difference of volumetric shrinkage through thickness. it represents the out-of-plane warpage.

Basically, Fast Cool(auto-grid mesh) and Standard Cool(solid mesh) have similar results. However, in some cases, especially for complex and thick parts, the results may differ.For example, in this case, the heat accumulation occurs in different area.
To avoid this kind of situations and achieve more precise results, we recommend using standard cool(with solid mesh) for the analysis.- 103 views
