How can I calculate and plot time-average velocity in Transient Simulation?

Islam Ramadan · March 5, 2015, 10:10

Hi Experts,
Could you please help me to calculate the time-average velocity for a transient simulation in the whole computational domain? Ever time, i get the velocity vectors for the whole at a certain time step.

How can i plot the time-average velocity vectors in the whole domain?
Thanks in advance

Check the box for data-sampling for Time Statistics, then run your simulation for a little while again.
Then you will get to see data (and plot vectors) for the mean values for velocity and pressure, as well as the rms values of these.

Thanks Very much, Vandeley

Hi, experts..

In ANSYS Fluent CFD, I applied data sampling for time statistics and got time average properties. Contours of time average properties is shown easily. but when I try to draw vectors of time average velocity, there is just a instantaneous vectors colored by *average velocity. I mean vectors do not change instantaneous to time average vectors. time average is shown by color only. here is only one option like *

Vectors of... velocity. phase.. water.. colored by..Unsteady Statistics.. Mean velocity Magnitude.. phase...water...

But, I need to show original time average vectors.

Please , guide me.. Thank you

Hello, how do you do,
Could you kindly tell me where I might see this data?
