The sketch illustrates the general layout of an interface between 2 neighboring components.
Primary/ Secondary
One side (component) of the interface is primary always, the other one is secondary. The primary side determines the position of the interface (red in the sketch), the secondary has to align on the primary side. Each interface side can define an offset to the interface optionally.
If the geometry of the primary component and therefore the position of the interface is changing, then the component with the secondary interface is adjusted automatically. I a component is deactivated (see Active/ Rename/ Delete), then no adjustment will be effected - therefore an overlapping of neighboring components is possible, which is illustrated by a warning (see Components).
Interface definition
The interface definition at volute inlet as well as at stator inlet and outlet is made in an uniform manner.

Rotor-Stator-Interface
Rotor-Stator-Interface (RSI) at impeller outlet can be defined in the CFD-Setup of the impeller, otherwise it's located directly on the impeller outlet.
Flow direction
Beside the geometrical information the flow direction is an important interface property. The flow direction at the component inlet is defined by the flow direction at the outlet of the upstream component (predecessor). Outlet flow direction of a component is determined by its blade or by constant swirl for vaneless components.
The first component of the project has no predecessor and gets the flow direction information from pre-swirl definition in the Global setup.
