To extract data over a circle

tyagikartik · April 19, 2016, 08:29

I am new to Tecplot. I have a 3D annulus geometry. I want the temperatures across the circumference of a circle at a specified radius. Can someone please help me?

Have you solved the problem? I hope I can get the solution. Thank you

One option is to compute a 'radius' variable using Data>Alter>Specify Equations.

For example:
{radius} = sqrt(X*X+Y*Y)

Then do the following:
1) Create an iso-surface based on 'radius'.
2) Extract the iso-surface to a new zone
3) Activate only the new iso-surface zone
4) Create a slice at Z=nnn, ensuring that the slice cuts through surface data.
5) Extract the slice to a new zone

This will leave you with line data at a specific 'radius' and 'z' location.

I hope this helps.

Dear Scott,

I have been trying to extract data over a circle in 2D using tecplot similar to polyline extraction. Is it not possible? How may I do the data extraction along a curved surface?
