How to plot the radius of a droplet's fall with Fluent
 
Hi everybody,

I just did a simulation of a blood droplet impact onto a solid surface with the VOF model. I have catched a sequence and datas at different time step.
But is it possible to plot the radius of the droplet depending on the time with Fluent ?

Thank you very much for answer,

Hi!

just an idea, i don't know, if this is working...

- create multiple lines perpendicular to the flight path of the droplet.

- every time step, plot the liquid fraction on every line. So you gonna have some plots that look like:

000000000000000000000000
000000001111100000000000
000000111111111000000000
000001111111111100000000
000001111111111100000000
000000111111111000000000
000000001111100000000000
000000000000000000000000

with that lines, you might calculate the droplet diameter (the coordinates, where you have a transition between 0 and 1).

No idea, if this will work.... And maybe there are much better possibilities....

Best wishes
Ralf
