1) Design Tool based morphing can be used to modify the geometry based on the adjoint solution 2) Under Deisgn Tool/Region, select Cylindrical as the bounding region geometry type 3) specify the intended morphing direction vector as the axis vector under Design Tool/Region Conditions 4) un-check the default option for Motion enabled along theta & radial direction, thus the morphing will happen only along the axial direction, which can be any user specified direction vector This way can also be used to constrain the morphing along theta & radial directions by un-checking the Motion enabled option for the respective directions
