Plot average of some fields
 

Hello,

I'm trying to plot the average pressure, speed and mass fraction of components in my simulation but I don't find a correct tool to do the whole average. I've found 'patchAverage' but it only gives me the average for one patch and not the whole domain. Is there a built-in tool in OpenFOAM to have this kind of average or do I have to use another tool ?

I'm using visit for visualization but I don't find how to plot averages in it.

Thank you for your help
