If I create a separate fluid volume inside the engine, the inlet and outlet become interfaces, which turn into internal boundaries in Fluent. How do I manage this appropriately for internal-external flow coupling?<\/li>\n<li>How should I apply the boundary conditions correctly? I need to ensure the boundary conditions for the far-field and engine components are handled properly.<\/li>\n<li>How do I prepare the geometry for this setup in SpaceClaim?
