Hi Dustin,

You can use the “meanmode” module of FieldConvert which compute the data on the zero Fourier plane. You can use it on the flow fld files, or even on Reynolds stresses fld files.

Hope this helps

Cheers,

Moshen

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
