Hello everyone, I am trying to make an inflation on certain walls for the near investigation. I need to avoid the high computational cost, so I chose to insert inflation into the determined walls. When I select one wall and select insert>> inflation, when I press "Apply" to the boundaries, it keeps saying that (no selection), and when I ignore it and press "Generate," the inflation is not created, and ANSYS tells me, "Please define a boundary for the inflation control.". Would anyone help me to fix this? Here are screenshots for the steps.

Hi walaakm10,

I think there is a confusion of terminology. I assume that you want inflation layers growing from a face into the domain. If this is the case, then under Scope->Geometry you should choose the full body and not the face. Then under Definition-> Boundary, you should choose the face. 

In your screenshots, I can see that for geometry, you have chosen face, and now it is asking for boundary. Boundary in this case will be an edge. Inflation then grows on that face alone, from an edge, which I assume is not what you intend.

Note: Pressing Ctrl+B, you can select bodies, and by pressing Ctrl+F, you can select faces.
