How to create a curved line over wall of bend pipe in fluent?
 

Hello

I am simulating flow in a bend pipe. I do need to analyze WSS and TKE at wall along axial direction. For this I need to create a curved line over the wall along which I can extract data.
I am able to create straight lines, but unable to make a curved line over the bend of pipe.
I have attached a figure of model for reference.

Please help!!!!!!

Thank you in advance!!!
