Wing Spanwise Averaging

sbuanzi · September 3, 2020, 08:24

Hi everyone,

I've got .cas&.dat solution files from Fluent of a flow over a wing. The 3D grid is basically a 2D mesh of the airfoil, then evenly extruded for some layers in spanwise direction with simmetry conditions at span ends (it's not a finite wing case).

I would like to compute the spanwise average of a variable, plot it as a 2D contour of the airfoil and write it as formatted text.

Can anybody help me?

Thank you in advance.

Hello sbuanzi,

I would start with extracting slices spanwise across your wing, and then take the average of these slices. There are a couple approaches you can take after that. One approach is you could create a variable with the average on the slices. Then, interpolate these average slice variables onto the grid. You could contour color based on this average variable after that.

Here is a PyTecplot script that is a step in the right direction which will extract slices:

Additionally, support@tecplot.com is a good resource if you want the Tecplot team to take a look at this question.
