inlet, outlet and body of a curved pipe not recognizable in Setup

Attiya221 · June 17, 2020, 22:44

Hello,

I am trying to simulate water flow through a curved pipe with a conical sweep.
I built the geometry using Rhino6, it generates drawing with .igs and many other extensions that Ansys Fluent can read. The final geometry was a poly-surface. I can import it and generate a mesh and an inflation, but when I reach the Setup stage, the Named Selection edges of the inlet and outlet are not visible in Boundary Conditions. I also struggled to generate the Boundary of the body since it only recognizes it when I use Smart Select for the mesh and the inflation.
I am hoping to get a velocity profile of the water flow but since the inlets are not recognizable, the Contours can not be generated.

please let me know if you need any files or information to help with this enquiry.

try following
make mesh in workbench mesher, define name selections

thank you for replying so swiftly.

I already created the inlet, outlet and body Named selections. They appear in below the mesh in the mesher but not in the Setup to be selected as the Cell Zone and Boundary.
