cfd_rookie_6 is on a distinguished road
Hello everyone,

I am trying to simulate an atmospheric boundary layer with a given set of boundary conditions (velocity w, k, epsilon) at the inlet (z=0) of the computational domain I’ve defined. The code I’m using converges without issues and saves the simulation results in a file where variables are stored as cell-centered data.

When I import the results file into Tecplot and plot the inlet profiles at z=0 (i.e., k=1, at the cell face), I notice a discrepancy in the cell values near the ground compared to the boundary conditions I initially set. It’s possible that this difference is due to the interpolation Tecplot performs when converting the cell-centered variables from my results file to face-centered values.

Alternatively, how can I verify through Tecplot that my boundary conditions have been correctly implemented?
