Hi there,

I have a finished OpenFOAM Simulation of a pipe which extrudes on the y axis.
Since it’s a turbulent simulation plotting over line doesn’t make sense because of the occurrence of Kármán vortex street. So I want to calculate the average in x and z direction for every y and plot that as a line plot over y.

I have gotten so far:

create a slice on a set position y
use integrateVariables Filter to get a sum as well as the area
use calculator to do sum/Area
So far so good but I want this (or anything which gives me the required output) to happen for every position in y. Placing hundreds of slices isn’t fun after all. Any suggestions?
