Moshen, Thank you for the helpful response! "meanmodes" performed exactly what I needed. I'm curious if there's a method to perform the spanwise average dynamically during computation time, meaning that the spanwise average is calculated per iteration, and this 2D plane is then averaged over time.

You can use it on the flow fld files, or even on Reynolds stresses fld files. Hope this helps Cheers, Moshen From: nektar-users-bounces@imperial.ac.uk <nektar-users-bounces@imperial.ac.uk> on behalf of Ma, Ting-Hsuan <TIM48@pitt.edu> Date: Monday, 27 November 2023 at 20:10 To: nektar-users@imperial.ac.uk <nektar-users@imperial.ac.uk> Subject: [Nektar-users] Homogenous Spanwise Averaging ⚠ External sender.

Hi all, I am currently working on obtaining DNS data and have successfully provided Nektar with a 2D mesh (XY) for streamwise and wall-normal directions. Utilizing Nektar's homogeneous expansion in the spanwise direction, I've managed to acquire my 3D turbulence data. However, I'm looking for a function that can return a 2D XY plane of all averaged components by averaging in the spanwise, homogeneous direction. While the Filter "ReynoldsStresses" can provide the 3D time-averaged fields, I was wondering if there's a function specifically designed performing the averaging/output that I have specified. I've checked the user guide without finding relevant information. Any guidance or pointers would be greatly appreciated. Thanks, Dustin
