I am trying to manipulate field files generated from spectral element solver NEKO (successor of NEK5000). I need a Cp vs x/c plot but I cannot identify the surface of the airfoil. Can you suggest if Paraview can manipulate field files (field0 and nek5000) to get this processing done.

Do let me know if you need any other info.

I could not give the exact simulation as its too large. There is a similar one done with a coarser resolution.

PlotOverIntersectionCurve should be what you are looking for:

Hello

Just a follow up question:  
Can I know if it is possible to extract reynolds stresses, overall lift, drag from fields?

Thank you  
Pranay
