In flow trajectories fluid is not flowing through the curved pipe. what is wrong i did?

I tried to make design of venturimeter and then flow simulation in cut plot animation fluid show in curved pipe but in flow trajectories fluid is not flowing . Please tell me what to do. I am trying this for first time.

Hi Sunny,

It seems ok to me when I run the simulation, I did have to add "vectors" and "streamlines" to cut plot 1 in order to view the flow in that cut plot, but the flow trajectories 1 feature worked fine, did you "right click > play" on it?

One comment, the mesh in the side tube is too coarse for accurate results, you will need to apply "local mesh", and adjust it such that you get at least 4 cells across the tube I.D., 6 or 7 would be better. There are several ways to accomplish this, best bet is to play around with it and view the results with an additional "cut plot" that shows the mesh.

this is how it is .

this is how it is looking but i don't think its perfect

Here's an image of flow trajectory1 after I refined the mesh in the venturi zone, with smaller arrows too.
