July 8, 2021 at 8:17 amaitor.amatriainSubscriberIn order to simulate the flow in the outer annulus, you need the geometry of the fluid part, while you have the one of the solid part.
Once you have the geometry of the fluid part, in ANSYS Meshing you can set the names of the boundaries by creating Named Selections. If you decide to use Fluent Meshing, then you can do the same by creating Groups in SpaceClaim.
July 9, 2021 at 11:30 amMechaSubscriberThank you for your help Possible Setup Conflict?
I have successfully obtained some test result(s), however, I am a bit confused. Figure_1 display how I set up the names for inlet/outlet and walls for one case, (I hope its explanatory enough). In Figure_2, I have compared the same solver setup with another name setup, (inlet/oulet and wall only).
Should the selection of how I apply my names to my boundary conditions affect the results and what can be the reason for the different results?
My opinion is that the the last picture of Figure_2 is the most realistic one due to the turbulence that would be caused after exiting the "barrier". In a generic view, which of them seem most reasonable?
