I am trying to create two inlets and two outlets for ventilation in two separate storage containers. I made holes in the Solidworks model for the inlets and outlets and imported this into ansys directly.

I tried to create named selections for the inlets and outlets in Ansys meshing, which I was able to do after sketching a surface on the cover of each inlet and outlet since I could not select the hole (see image below).

The problem is that the named selections I created do not populate in fluent when I complete 'setup,' and I have tried updating upstream data and closing/reopening all applications.

My questions are: (1) how can I get my named selections to populate in fluent so I can give them inlet and outlet characteristics? and (2) am I adding the ventilation properly?

Any and all help would be greatly appreciated!

Hello Have you made sure that the fluid geometry is correctly extracted?
When you create the named selections in Ansys Meshing, are you using the surface filter to pick the correct surfaces? Could you please share a screenshot?

Hello,
Can you try to import the geometry to spaceclaim, apply named selection and then bring it to Meshing?

this is how I have been creating the named selections in Ansys Meshing.

Hello Is the surface part of the any solid geometry? Or have you created this additional surface in SpaceClaim?
What I'm asking is: in meshing, do you see these inlet and outlet boundaries as surface bodies or are they part of solid bodies? Your geometry seems to indicate that you have some surface bodies (highlighting it below).
If this is the case, instead of having additional surface bodies, could you please try and create these surfaces directly on your Fluid volume? You will not have any surface bodies (all solid/fluid volumes)
