Hi everyone,

I have a question about the point settings in bubbly flow mode in comsol 3.5a.

After I select one point, I am asked to set the pressure value. What is the definition of this pressure? Should it be 1atm, or should it be the difference between the real pressure in the simulation and 1atm?

Similarly, I have a problem in comsol 4.2a. I am asked to set the value of the reference pressure. What is the definition of the reference pressure?

Any help will be greatly appreciated!

Thanks,
Xiaofei
