Hi, dear all,
After a few years away, I am now back to this forum, so glad to see it is still so many people there.

I am now working on a Kaplan turbine with non-constant tip clearance, but I have found that I can not decide the tip clearance with a length variation from the leading point to the trailing point with my own rule.
In TurboGrid, it seems that people can make a non-constant tip clearance by choosing "Profile Number" if he has a profile layer which is decided by the user himselfcan serve as the end of the blade.
But however, in BladeGen, the points on a profile layer are decided by the system with a fixed ratio from the hub to the shroud, people can only change the ratio for a layer altogether, but can not change for each point seperately. So that means, I can not control the tip clearance with my own rule.

Is there any solution for it?
I really appreciate for any hints, thanks
