Hey there,

I am new to Ansys and I have some struggles with the named sections. I want to create a box (2D) with several inlets at the bottom. So I already tried it multiple times and it always worked - i created a mesh and named the inlets (f.e. inlet1, inlet2, ..), then they appeared in the boundery conditions in Fluent.
Now i created a bigger box with 20 inlets (before i worked with 3-4). There is no other difference to the meshes i created before, i named the inlets as i always did (inlet1 - inlet20). But: In Fluent, only inlet3, inlet4, inlet7 and inlet10 appear and I miss the other ones (they also do not appear in other groups like walls …). They all have the same characteristics, and for all of them "send to solver" is activated.

Can anyone help me with this problem?
Thank you!

Are you doing named selections at CAD or at Meshing Stage? It is better to do it at meshing stage. I am afraid I could not access the images; it would be better if you attach those images directly with the post instead of using 3rd party links. The option is right above the text box when you are writing a post.

As far as names are concerned, if the inlets are geometrically separated from each other, then you may do it within Fluent as well.
