Hello Respected Fellows,

I am simulating liquid jet focused by co-flowing gas.
My aim here is to get liquid jet length and diameter before it breaks into droplets after it exits from nozzle.

Currently I am using swak4Foam for the purpose and I can get the diameter by using something like

(alpha1 > 0.5) ? pos().y :0

which give me diamater properly.
but for the case of length i do the same as for diameter using "pos().x"
the problem I am facing is that it keep giving me the length untill the jet breaks into drop as the drop is still "alpha1>0.5"

in other words I want to get the max x position till jet tip vs time.


If some one can help me setting this thing up i will be very thankful.

Regards,
Rizwan
