About BladeModeler
BladeModeler is a new blade geometry creation product (Windows OS only) that consists of three components:
BladeGen – Blade creation and editing tool
DesignModeler – Workbench CAD solid modeler
BladeEditor – Add-In to DesignModeler that can import and convert BladeGen geometry into a solid model

Splitter Blade
Note on the Geometry and Inlet Gas Angles tab, the number of intervanes is equal to the number of main blades
This means our impeller will have one splitter blade per passage
Click New Model to build the model
When prompted, save geometry as filename impeller1.bgd

Join Hub Curve
To facilitate creating a fillet in DesignModeler, join the middle and downstream hub segments:
Select the point at the intersection of the hub and trailing edge in the meridional view
Right click > Segment Operations > Join Segment at Point

Create TurboGrid Files
TurboGrid is used to create a high quality, hexahedral mesh for CFD
Export the data for TurboGrid
File > Export > TurboGrid Input Files…
Four TurboGrid files will be created
.inf file containing machine info
Hub, shroud, and profile curve files
Click OK to write the files
See TurboGrid demonstration for more details on the power of using TurboGrid!
