Hope it helps.

Thank you Hrushi. The hard job is done; It compiled fine. I simply ran the application after my simulation run time was complete and it printed out the value. Is there a way to extract the data from the barycenter into a file so that I won't have to manually copy the data? Have a nice weekend.

Hi,

Here is the updated version of baryCenter (for OF-2.2.1) baryCenter221.zip utility. I have tested it on OpenFOAM-2.2.1.

Enjoy!

Dear Sebastian,

i want to compute the rise velocity. After you got your center file and you use it in Matlab, how do you compute exactely the rise velocity for each time step?

v(n-time) = ( barycentre(n) -barycentre (n-1) )/ deltaT

or

v(n-time) = ( barycentre(n) -barycentre (0) ) / ( t(n)- t (0) )

??

Thanks in advance

Marco

Hi Hrushikesh
Thank you for provide baryCenter..
But,how I can use this?I simulate rising bubble and I want calculate rising velocity,bubble diameter and surface area..but I don't know how define these??
can You help me??
Best
