I'm modeling the flow around an elliptic body. Instead of angling the current, I angled the body. Now I need to create a series of curves normal to the body to report the pressure coefficient. please guide me.

Hello,

For us to understand your requirements in a better way, can you show the illustration of how you want the polylines?
However, you can try using 'Boundary Intersection' method for creating the polyline at an angle. You need to create a reference plane at an angle (as per your requirement) and intersect it with the boundary surface (of your interest) to create a polyline at the intersection of the plane and the surface: 12.1.10. Polyline Command (ansys.com)

Hello,

I think you have created a solid surface using CAD. Correct me if I am wrong?
What I mean to convey, you have to create a reference plane in CFD post itself and use the Boundary Intersection method to create a polyline.

You'll need to orient the plane if you're in Fluent.
Getting the intersect is a different matter, and not easy. My usual approach is to keep the object of interest aligned with x, y & z and adjust "outside" to suit my needs.
