Hi all,

I have been given a CAD file of a pump impeller which I would like to import into BladeGen so that I may parameterise the design intent of the impeller to perform optimisation.

 

However, after using the data import wizard, I get unwanted nonsmooth blade surfaces near the trailing edge.

 

 

I believe this is due to the "Select Tangency Points" step of the data import wizard completely messing up the trailing edge definition.

 

I have spent days on trying to fix this. I have read the relevant tutorials (the few that exists) regarding using the data import wizard. I have also searched on Google and the forum for relevant posts, but nothing seems to be much help.

If anyone is able to answer any of the following three questions, I would be eternally grateful.

1) Have you managed to successfully use the data import wizard? If so, could you please provide advice on how to get a smooth blade surface?

2) Do you have any advice for importing the geometry into BladeGen so that I can modify the design parameters to create new geometries?

3) Alternatively, do you know of any other methods of extracting the design intent of the blade so that I may parameterise the geometry for subsequent optimisation?

I am happy to provide necessary CAD files or TurboGrid files (containing hub, shroud, and blade contours) if required. Thank you in advance for any help you can provide!
