Hello,

I would like to calculate a simple relation in ParaView.

I want to subtract turbulence intensity at the lateral surface from the turbulence intensity at the centre line.

The relation I want to calculate is:

I^2 = Iw^2 - Ia^2;

Iw: turbulence intensity at centreline
I0: turbulence intensity at the lateral wall.

How can I plot the contour for I?

I want to subtract Ia at all x positions of Iw in the domain

For clarity, find attached a sketch of the domain

Thank you
