2D color plot from 3D data
 
2 Attachment(s)
Hi

I have some data defined over the surface of a pipe, and I want to print them on a 2D color map. In order to visualize all the result in a single 2D plot, I would like to use a polar coordinate system (r,theta,z) instead of the cartesian one, and use theta and z as axes for the plot.

How I can do it?

In the images there is an example, made with Tecplot:

Greetings Nicoḷ,

I haven't confirmed this, but I believe the either the "wrap by scalar" or "wrap by vector" filters should do what you want:
Best regards,

Bruno, thanks for the suggestion.

I have obtained the result in the image, using the "warp by vector" filter:

Then I can use "Extract Cells By Region" to remove the deformed cells in the area in which the warp filter cuts the geometry, and a "Clip" to remove the irregular boundaries. The final result is this:
