### 10.6.5. Export as Meanline Data (.rtzt file)

To export a file that contains the camberline/thickness definitions for a given blade row, create an ExportPoints feature. Start by clicking the icon.

The feature properties are listed below:

Table 10.7: Details View for the ExportPoints feature: Meanline Export

Details of [Feature Name]
Export Points | [Feature Name]
Export Type | [Meanline | TurboGrid]
File Name | [File name] This property indicates the name of the file that is to be exported.
Blade | [Blade feature selection] Select a blade to indicate the blade row for which data is to be exported.
Point Distribution | [Uniform in M | Uniform in camberline length]
Number of Points | [Value>1]
Output Layers: [a]
Output Layer 1? | [Yes | No]
Output Layer 2? | [Yes | No]
Output Layer 3? | [Yes | No]
[a] Layer items are listed for all layers defined in the Flow Path. Specify which layers are to be used in generating the meanline data.

Upon generation, the meanline data for the applicable blade row is written to a file that contains r, theta, z, and normal thickness data. Note that this file will not appear in the Files view of Workbench.

Meanline data is exported based on the camber surface and thickness surface data represented internally. Therefore, this data may not be representative of the blade if solid model operations have been made to the blade geometry.

An ExportPoints (Meanline) feature defines the point output for exactly one blade row. All blades in the selected blade row are exported. A multi-blade row model would require multiple ExportPoints features to output data for more than one blade row. All blades (the main blade and all existing splitter blades) in a single blade row are exported by a single ExportPoints feature. Regardless of whether you select a main blade or a splitter blade when defining the Blade parameter of an ExportPoints feature, the Blade parameter will always display the main blade. If you suppress any blade in a blade row, the ExportPoints feature for that blade row will also be suppressed.

The ‘Number of Points’ property specifies how many points are exported from the leading edge to the trailing edge for each blade. The number of points upstream and downstream of the blade(s) is determined by the length tolerance and the shape of the flow path contours.

The Blade selection lets you select the Blade feature of interest. However, all blades in a blade row are exported.
