no surface tension option at polyflow

[mn2n25]

hello i am running a 2d extrusion simulation with the following boundry conditions at fluent polyflow 

inlet>> inflow >> normal velocity which is the value of the velocity of the entering fluid 

outlet >> out flow>> normal velocity which is the value of the velocity of the fluid that exist the domain 

left and write boundarries are free surface luike a hollow core cylinder 

the problem is that  i cand see surface tension option when consider a boundry as a free surface you can see my options on the following screenshot. i sont see any surface tension to activate .
