Training Manual

BladeEditor:

Blade Topology

FEA meshing is often easier when the blade is created with four primary faces (not including root and tip)

Blade topology is controlled by the Merge Blade Topology property:

No means always create the blade with six faces: pressure side, suction side, leading edge, trailing edge, top and bottom

Yes means merge the faces when they are tangent

Faces not merged

With faces merged

Fluid Enclosure

BladeEditor optionally creates an Enclosure for the

periodic sector of the fluid zone

Training Manual

BladeEditor:

Updating the BladeGen Model

The imported BladeGen model can be updated to reflect changes made in BladeGen

The Refresh property of the ImportBGD feature controls the update:

Yes (default) means that the BladeGen model should be re-imported whenever the source BGD file changes

No means do not update the model

If Refresh is Yes, the BGD file will be checked and re-

imported, if necessary, when

the model is re-generated

This allows design changes in BladeGen to be

propagated easily to

DesignModeler

Training Manual

BladeEditor:

Updating the BladeGen Model

Any changes or features added to the geometry in DesignModeler will be preserved, except:

If the hub contour has changed, it may need to be manually adjusted to fix the hub loop

If the number of contour segments has changed, any DM features added that depend on the edge or face topology may need their selections adjusted

Break in the

hub loop
