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!

The solid geometry could be sent to Simulation for structural
analysis
The fluid domain could be sent to CFX-Mesh or ICEM for
meshing
