uconv in single-point-stats.py

[zz-blue]

@soaringxmc @chenjiaweiDr
In single-point-stats.py, uconv seems to be used for adjusting the wall velocity, as shown in the following code:

utau_s = ((u1[0] + uconv) / zc[0] * visc)**0.5

I would like to ask how the value of uconv is determined. Is it related to the inlet velocity, free-stream velocity, or some correction term? Are there any recommended approaches or theoretical references for setting this value, particularly in turbulent channel or boundary layer flows?

Hi, thank you for the post!

We have added input.py to examples/les, which should be the input file for single-point-stats*.py. Also, explanations of the variables have been included. Hope it is helpful to you.

uconv is typically set as zero, except if you solve the flow in a convective frame, which is not typically used.
