I have defined all named selections correctly in the mesh environment. However, when I transfer it to fluent, it changes one of the regions from inlet to interface --> wall.
How could I force this region to be an inlet?February 1, 2022 at 11:39 amRobAnsys EmployeeWhich region? Inlets can only have cells on one side, so check the model.
February 1, 2022 at 1:43 pmErickLuoyingSubscriberHello Rob The image below shows what must have happened (this time from Fluent Meshing environment where Fluent has correctly considered the boundary conditions (in this case, an inlet)).
But when I use the same geometry by Mesh environment, Fluent considers an interface and not an inlet (as shown in the first comment).
February 1, 2022 at 1:50 pmDrAmineAnsys EmployeeWhat do you mean with Mesh Environment?
Anyway: you can always change the type of boundary at solver stage.
February 1, 2022 at 2:25 pmRobAnsys EmployeeIf you're using Workbench Meshing you can find surfaces in close proximity to be falsely flagged as interface pairs. Fluent Meshing doesn't have a check so won't do this. In Workbench Meshing look in the Contacts section and see what it's doing: if you have share topology active there shouldn't be any contact pairs.
