Dear all,

I have a mesh in ANSYS ICEM (v19.2) of a cilinder (D = 0.02 m, L = 0.5 m ) with and internal circle (d = 0.018) at Z = 0.03 m. The fluid should go from the inlet to the outlet, passing by the internal wall which leaves a little space for it to pass between the external cilinder and the circle. I have all the sections named. The circle is a wall, and is also set as a boundary condition ("output mesh > boundary condition). However, when I read the mesh in Fluent, the internal wall of the circle is ignored and joined with the interior of the cilinder. How can I fix this?

If someone can help, I could show the files by email.

Best regards,

Thanks a lot!
