How to find the values of pressure and velocity into each cell?

LeaIna · September 21, 2018, 21:14

Hi, guys!

I'm new in OpenFoam and my university professor wants a graph whit the U and P. However, it requires the values of each cell and the graph will be generated at the gnuplot.

I need values each cell of the mesh. How to find ?

( I can't to find through of modification of the file, it has to be manual)

can someone help me ?

thank you !

Hi,

If I understood the topic right way, I could suggest the following solution using paraView:

- Open paraView and import the data

- At the right side of the screen choose Split Horizontal

- From the list choose the last one namely SpreadSheet View

- From Attribute choose Cell Data instead of Point Data

- (optionally) At the right screen side choose Export SpreadSheet

done

Regards

Peter
