Center of Gravity and Raise velocity of Bubble
 

Hi Foamers,

I simulated raising bubble case proposed by Hysing et al. (http://www.karlin.mff.cuni.cz/~hron/...3/1934_ftp.pdf) in 2D using OpenFOAM 5.0. I would like to calculate the center of gravity as well as raise velocity of the bubble at different write time steps before getting on to my final time (t=3).

I tried to use swak4FOAM to do this. But my FOAM version is 5.0 and I couldn't find it compatible. I am using paraFOAM for post processing.

Help me out with some best possible way to calculate the C.G and raise velocity of bubble.

Thanks in advance.
