You can apply enforced displacement with SPCD too. SPCD is usually used in FRF analysis to define displacement, velocity and acceleration. For applying angular motion, you can select and enter the values in dof 4,5,6.

Hello Rajashri,

Thank you so much for your answer.

I have additional query on this. May I know difference for the enforced linear/angular motion with SPC & SPCD card.

Thanks,

Jaya.

Hi Jaya,

The 1st pic depicts that you are constraining the model in 1236 dofs and in 2nd pic you have constrained the model in all 12356 and applying enforced rotational motion about X-axis.

If you had applied the value in dof1, then it is enforced displacement in X-direction.

Thanks
