Boundary conditions

Hello,

Can anyone tell me why I have this elements in the boundary conditions, and how can I reduce the number?

Thanks.

Greetings!

If you've imported the geometry from another software, or you haven't created named selections in ANSYS Meshing then Fluent may not know which boundaries to group. Combine boundaries and cell zones via Setting Up Domain > Combine > Merge...

Yes , I have imported the geometry from autodesk inventor.

Thanks, I will try that.

Please, can you tell me where is the setting up domain menu?

Thanks!

They've updated the GUI in ANSYS Fluent 17, it was previously located elsewhere (check the menus at the top of Fluent; merge zones will be there). If you still can't find the menu, then see the users guide under merge zones for step by step instructions.
