integration in postprocessing
 

Hello,

I need to integrate the following equation for all time steps.

U(y) is instantaneous velocity from simulation. y is in vertical direction and C is a constant. I need to calculate it for every meshgrid in x direction (streamwise).

Anyone can help?

Thanks

Hi
I'm also facing this problem. I found this

But I can't compile the code, with the error without .dep file. Perhaps the code only works for of-1.6.

I'm a little confused about the integration in openfoam. If I want to integrate a variable, is it means that sum(U*dL)/L，U is the variable value on the cell center and L is the direction you want to integrate, dL is the length of the cell in this direction
