Hey everyone, this is my first thread ever so if i am not respecting the norms of the forum please forgive me.

Currently i am trying to validate OpenFOAM LES model using a planar jet. I want to compute the jet half-width, longitudinal velocity profiles, etc and am wondering if any one can explain me how to do so.

I have the cellcenter coordinates and the velocity fields for every time step of interest so i just want to write some code for OpenFOAM that, e.g. for the jet half width:
1- computes the cell and centerline velocity average;
2- compares the cell and centerline average velocities and in case it corresponds to 1/2 of the centerline velocity, that cell coordinates go to a matrix;
3- does this for every time step (every velocity field that is in my case directory);
4- Average of the yy positions over every time step for a given x position -END.

Moreover, how can i extract the SGS turbulent viscosity?

The paper that i am following for this work is the following:
