The Bubble pressure result shows the pressure of the gas inside the bubble distributed across the part.
This result is generated from a Microcellular injection molding analysis, for the following mesh types:
Midplane 
Dual Domain 
3D
Using this result
The Bubble pressure result is very useful for checking whether there are any pressure spikes. This is normally a sign of imbalance. Normally this can be fixed by changing gate location(s) or the amount of gas injected into the polymer. Sometimes only a subtle change is necessary.
Note: For models with midplane or dual domain mesh types, the Bubble pressure result is only available if the Number of profiled results specified in the solver parameters is greater than zero.
Things to look for
- If the bubble pressure is too high, warpage may occur. It is recommended that the bubble pressure be kept as low as possible.
Note: Changes such as those above, can only be made using a licensed product.
