Meshing using curvature
 

Hello everyone

I want to generate mesh like uploaded first picture.(Desired mesh)
I want to generate mesh finely for only curved part.
But I couldn't.
If I generate mesh, it becomes like uploaded second picture.(My mesh)
Every meshes in this geometry becomes fine.
You can see Auto mesh from uploaded third picture.(Auto Mesh)
And option that I've handled is in fourth picture.(Option)

I want to generate mesh like first picture, but what is the problem in my option(fourth picture)?

Thanks :)

I think in ANSYS Meshing you need to create a named section and then set a different minimum sizes for that particular section.

Oh I've solved it by changing geometry as 2D.
Because pipe flow is symmetry, I've changed geometry into inside 2D plane.

Thanks :)
