Hi,

i am trying to fit my target geometry of an axial turbine blade.

when i initialize it, it does not fit properly.

however, after coarse fit, the target geometry is caputred much better but still at trailing edge it does not capture the target ( i have also tried fine fit and increased bounds of blocked free parameters but still could not caputre trailing edge
target shape accurately)

The data of turbine blade was in unstacked z,y form (untwisted blade). I converted y to theta using th=asin(y/r) where r= radius at hub or tip.

before initializing i stacked the blade at center of gravity in autoblade as mentioned in experimental data.
kindly advise.

thanks,
i tried to upload some pics but size was big. i can email.
