[OpenFOAM] paraview : how to save a "selection over time" graph ?

Cyp · June 8, 2012, 15:07

Hi!

I am carried out a calculation over a 3D vertical tube. I know how to plot the average value of a field (pressure for example) at a region of the tube with "plot selection over time".

How can I save this curve into a text file ??

Best regards,
Cyp

I finally found the solution :

- select the region
- "extract by region"
- "integrate variable"
- select the variable you want to plot in the intragrate variables table
- "plot selection over time"
- in the object inspector panel, click on "information", then select the data array you want to save in a text file (p or U for example)
- Then, file>save data.

Hello Cyp,
I am also trying to plot graph of mass (kg) over time but i have mass fraction results. I want to see the total mass injected in the full domain. Is there any way to check that on paraView and then plot over time?

Regards,
Umer
