I know the options to generate a line/rake surface to then plot XY data on them. Is it possible to plot XY data over an arbitrary curve (e.g. a spline).February 23, 2022 at 6:24 amNikhil NaraleAnsys EmployeeHello,
You can plot XY data on a line connecting a series of points. You won't get the exact curve here, but increasing the number of points may serve the purpose. This is possible using the CFD Post.
There is an option to define 'Polyline' where you can define the line as per your requirement. If you have the coordinates of the line, define it in the .csv format (Refer the link).
Polyline: 12.1.10. Polyline Command (ansys.com)
How to define a line in .csv format: 8.8.1. Export (ansys.com) (Refer section - 22.214.171.124.1. POLYLINE Data Format)
I hope this helps.
February 25, 2022 at 5:11 amFluxLimitedSubscriberthanks for the suggestion. Is there any way to accomplish this in FLUENT post-processing instead of CFD-Post? CFD-Post seems to choke on loading this file and doing any manipulation. It's about 20M 3D cells. FLUENT has no problem post processing it.

I doubt there is any direct way of doing this. But there is a manual workaround in Fluent.
If you have the line/curve equation or the coordinates, create multiple points from the Results -> Surfaces -> New -> Point. Once you have sufficiently enough points, plot the X-Y plot using these points and the variable of your interest.
March 8, 2022 at 9:13 amRobAnsys EmployeeThe other option is to look at using the intersect of two surfaces. If the line is on a curved surface (wing or the like) create an iso-surface of position and make sure the wall/surface of interest is selected when you OK/Apply/Create the new surface. That gives a "surface" that's the line common to the two surfaces.
