Hi,

You can go for making a spring element and apply PBUSH property and enter the directional stiffness value you have.

I am using CELAS1 and PELAS for stiffness data,  and my rotation direction is X so i am using CELAS in dof4?

IS it correct method?

Pradeep,

 

Yes, you can use CBUSH or CLEAS1. in your case Stiffness is around X which is Dof4
