F-Packing Function
 

All would like to know if anyone did compare results between Default f-packing vs Reduce surface breakup in extreme cases? Is the 2nd option run slower due to additional surface treatment needed to prevent breakup of fluid?

The difference in speed between different F-packing options is minimal. I doubt it will even be noticeable. The difference in the results depends on the type of problem and in many case is also minimal. I would recommend sticking to the default setting.

Hi Michael, thanks for clarification. :)
