Modeling a falling stream of liquid in air: Time-dependent vs. Stationary

Please login with a confirmed email address before reporting spam

I am trying to model the shape of a stream of oil falling down from a tap to familiarize myself with laminar two-phase flow. By editing the oil drop example in the model library, I was able to solve the time-dependent model. I can use the final time step to see the shape of the oil stream, but I would like to know how to find a stationary solution, since the time-dependent behavior isn't important to me.

I have tried replacing the time-dependent study step with a stationary step, but when I do this, the solution given is no different from the initial conditions.

I have attached my working time-dependent model. Thank you for any help or suggestions!
