Francis turbine analysis
 

I am performing a cavitation analysis on a francis turbine, and have already made an approximate model of the runner on pro engineer wildfire. Due to the absence of some engineering drawings, the blade profile is not completely accurate but is a good estimate. I transferred the IGES file to Gridgen v15 and did the needful, but when i open the CURVE files in turbogrid, the blade profile is completely skewed and the hub and shroud are nowhere near the original model...

help please

thankyou and best regards

Hasan,
Can you send me your IGES file, may be I can help you out, if you have not already rectified it.
