How to model a 1D spring

Good day Altair community,

I was wondering if someone could help me add a spring to my Hypermesh model.

I have modelled a carbon tube, one side has a boundary condition and the force is applied roughly in the middle of the tube. I have spent the last few days trying to model a spring on the opposite side of the Boundary condition (to model a rope that supports the beam).

I created a node with a boundary condition and used the 1D spring to connect the node with a node of the carbon tube. But this always results in an error message:

 

*** ERROR # 1309 ***

 Duplicate SPOINT ID 48845 - it is used on GRID card.

 

Using: Hypermesh 2023.1

               Mech. Solvers 2022.3

 

I would appreciate any feedback on what I did wrong.

Thank you for taking the time to read my post.

Kind regards Jens

    Hi Jens,

    I went through your model and found that C1, C2 fields for CELAS1 is blank.

    After editing it to 1, the model runs. Also, I segregated the spring to a different component and assigned spring property. Attached is the file for your reference.

    Thanks
