Hello,

I am running an unsteady simulation on a bluff body. I want to show the time-averaged flow field using streamlines. I was able to create a monitor and a contour scene representing this. However, when trying to create streamlines it does not show the time-averaged result. The mean velocity field function is not listed as one of the options for streamline field function.

Is there a way to display the time-averaged velocity streamlines on a scene?

Thanks in advance

I was able to create a monitor

You mean - Mean monitor?
Streamlines require vector field, so you'll need three mean monitors (of three velocity components) - and then define vector field function from them.

HI,
Thanks for replying

Yes, I created a field mean monitor. But i only tried the U component.

That is actually helpful,thanks!So I have to create 3 mean monitors with respect to each velocity component, u,v,w, which would create 3 field functions. On creating the vector field function, do you know what the definition syntax would look like to bring all 3 together?


Thanks in advance

On creating the vector field function, do you know what the definition syntax would look like to bring all 3 together?

When you define vector field fuction:
- set its type to Vector in field function properties;
- syntax is:

    [<i-component>, <j-component>, <k-component>]

i-oriented unit vector would be

    [1, 0, 0]

radius-vector would be

    [$$Centroid[0], $$Centroid[1], $$Centroid[2]]

your case would be something like

    [${MeanofVelocityi}, ${MeanofVelocityj}, ${MeanofVelocityk}]

I'm not sure it would be "MeanofVelocityi" or something similar, you can check that at properties of the mean monitor (there is a read-only name of the function), or just look through the available field functions.

Hi,

Thank you so much ,that helped
