[OpenFOAM] Time Averaged Streamlines

najunaju · January 24, 2013, 06:41

Dear all,

Hope you are doing well.

I am a new openFoam User. I would like to plot time averaged streamlines. Is it possible in openFoam.

For post processing, I am using paraFoam.

Any kind of help, will be highly appreciable.

Greetings najunaju and welcome to the forum!

Could you explain what exactly do you mean by time-averaged streamlines? Because from what I'm imagining, it's not possible to do an time-average of the streamlines themselves.

The best you might get is to do streamlines of the time-averaged velocity. If that is what you want, then you should apply the following sequence of filters:

"Temporal Statistics". It can calculate the average, maximum and minimum and standard deviation of all loaded fields.
"Streamlines", but apply them to the the output of the previous filter. I.e. make sure it's selected in the Pipeline Browser and then click on the streamlines button.

Best regards,
Bruno
