Hi friends
I have a problem to create a rotor geometry of an axial turbine. In fact, when i use from following path to shift model, geometry of blade changes. Why?
Tools>shift in z direction
Also, the pictures have attached.
Thanks a lot

You only shifted your meridional path. Your meridional path is defining your inlet and outlet points of your domain. Your blade geometry should lie in this area, in order to generate the blade as wanted.

Is there a reason why you need to shift the path in the first place? Either move the blade profile as well, find a room that shifts both or, if you use CFX or fluent later on, shift everything there using the transform function.

Thanks for your answer
I am designing stator and rotor together.
The stator and rotor must be correctly aligned in terms of spatial coordinates.
The spatial coordinates of the stator output should be equal to the spatial coordinates of the rotor input.
Can you tell me exactly which directiry I should do this work in the BladeGen to solve the problem?
