Hi,

   Can anybody tell me where to use spring element. I have created spring element with CBUSH card image and in property I have given PBUSH to spring element. I have given stiffness value in K1,K2,K3 and rigid value in k4,k5,k6. But it is showing following error in solving. 

   Also, can anybody tell what is analogy of spring element in optistruct.

    Hi @Bhushan D. Neve

     

    CBUSH elements need a coordinate system. If you want to use basic coordinate system keep the CID for all CBUSH elements to zero

     

    Select all CBUSH elements>> Card edit>> Select CID and leave it to zero instead of blank.

    Bhushan,

     

    Select all the CBUSH elements and card edit (shown in image) and change the CID.
