Stator extent has to be considered in relation to its inlet and outlet. These 3 areas are coupled, i.e. one is inherently defined by the two others.

Extent from inlet to outlet can be defined by 2 alternative possibilities in principle:
1. Center line
| • | preselection of extension direction:Radial, Axial, Tangential (to outlet of previous component), Free form |
| • | Definition of axial extension Δz and radial extension Δr or length L and angle of center line to horizontal direction ε |
| • | Definition of end cross section (Inlet or Outlet) by width b and angle to horizontal direction γ |
2. Hub, Shroud
separately for hub and shroud:
| • | preselection of extension direction:Radial, Axial, Const. area (with respect to opposite side), Tangential (to outlet of previous component), Free form |
| • | Definition of axial extension Δz and radial extension Δr or length L and angle of hub/shroud to horizontal direction ε |

The angles ε and γ are defined by 0° horizontal right and rising in counter clockwise direction (mathematical positive). A menu with some default angles is supporting angle input:
|
0° 180° 90° 270° Perpendicular: ε perpendicular to inlet or outlet cross section Parallel: γ parallel to inlet or outlet cross section |
Depending on the interface type the extents are defining the inlet or the outlet of the component. If the stator has the primary interface side at outlet the extents will modify the outlet. Otherwise if the stator has the primary interface side at inlet then the inlet will be defined by the extents.
|
If the neighboring components are primary both at inlet and at outlet then the extent of the stator cannot be specified explicitly because it's clearly defined by these interfaces. |
