34.3.11 Define/Turbo Topology...

The Define/Turbo Topology... menu item opens the Turbo Topology dialog box.

Turbo Topology Dialog Box

The Turbo Topology dialog box allows you to define the topology for a turbomachinery application, so that you can use the turbomachinery-specific postprocessing features described in Section  29.10. See Section  29.10.1 for details about the items below.

Controls

Turbo Topology Name   specifies the name of the new topology.

Boundaries   contains radio buttons for the topology boundaries to be defined.

Hub   specifies the definition for the wall zone(s) forming the lower boundary of the flow passage (generally toward the axis of rotation of the machine).

Casing   specifies the definition of the wall zone(s) forming the upper boundary of the flow passage (away from the axis of rotation of the machine).

Theta Periodic   specifies the definition of the periodic boundary zone(s) on the circumferential boundaries of the flow passage.

Theta Min, Theta Max   specify the definition of the wall zones at the minimum and maximum angular ( $\theta$) positions on a circumferential boundary.

Inlet   specifies the definition of the inlet zone(s) through which the flow enters the passage.

Outlet   specifies the definition of the outlet zone(s) through which the flow exits the passage.

Blade   specifies the definition of the wall zone(s) that defines the blade(s) (if any). Note that these zones cannot be attached to the circumferential boundaries. For this situation, use Theta Min and Theta Max to define the blade.

Surfaces   contains a selectable list of the available surfaces, from which you can select the surface(s) that represent the boundary selected under Boundaries.

Surface Name Pattern   specifies the pattern to look for in the names of surfaces. Type the pattern in the text field and click Match to select (or deselect) the zones in the Surfaces list with names that match the specified pattern. See Section  29.10.1 for information about matching additional characters using * and ?.

Surface Types   contains a selectable list of types of surfaces. If you select (or deselect) an item in this list, all surfaces of that type will be selected (or deselected) automatically in the Surfaces list.

Define   defines the new topology. If you have selected an existing topology the Define button is replaced by the Modify button.

Display   draws the defined topology in the active graphics window.
