1) After running the adjoint solution, using Design Tool based morphing, the directional morphing can be controlled directly along the Pincipal Axes 2) From Design Tool/ Region Conditions tab, the option for Motion Enabled is by default checked-ON for all the X, Y & Z axes 3) Hence, we can control morphing direction by checking or un-checking the motion enabled option for the respective axes 4) for ex., un-checking motion enabled for X-axes will give me morphing constrained along Y & Z axes, or only keeping motion enabled for X-axes ON will allow morphing along the X-axes only, and so on
