[Paraview] PV 3.8.0 averaging variables along multiple span lines

[Adriano Gagliardi]

Stephen,

By averaging, are you trying to compute the lift/drag forces? If so, do the
following:

1) Generate Surface Normals (requires vtkPolyData as input, so you may have
to use Extract Surface first)
2) Multiply it by your pressure variable using the Calculator.
3) You can then integrate up using Integrate Variables to get the pressure
force in the x, y, and z directions (this includes the face area).

If you are doing this for a 2D line, make sure to do items 1) and 2) first
before taking your slice and applying 3). 

Cheers,

Adriano

I have a cylindrical mesh and would like to average the variables in the
z-direction (span direction) for each x,y value (or theta=constant).
Can this be done in ParaView 3.8.0?
Hope my question is clear,
Stephen
p.s.
Presently I do a slice in the z-direction followed by a "plot over sorted
lines" to get the surface pressure coefficient.
