How to define an axis equation?
 

Hi all,

I'm student doing an internship on flexible risers, and to carry on my simulations, I found the catenary equation.

Here my question: how to define my revolution axis on Design Modeler?
like a UDF for example..

Is it possible to use APDL only to define the geometry, and then continue with Mesh and fluent?

Thanks a lot for your help.

Regards
