Hi,

I'm trying to plot an XY graph of Nusselt number along this surface, however it is an uneven surface and I don't know how to create the line. It needs to be centred along the pipe length, which is a ribbed surface. Is there a way of producing a line which runs along this curved surface to take data from.

In addition to this, it needs to extract data as if it is a 2D surface (rather than following the ribbed surface). This may sound counter-intuitive but I just need data as if the surface was flat (going along the pipe length) and not the additional length that would be caused by essentially flattening out the ribs in the XY plot. To look like the second image with x-axis being length along the pipe...

Hopefully this isn't too confusing, I will try to clarify if needed.
