replacing the node

Hello all,

 

I am creating a beam element connected between two nodal rigid bodies with the line 

*createspotweld $x $y 0 0 0 0 0 ''

 

Where x and y are the independent nodes of 1st and 2nd NRB respectively. When I look into file for generated beam element in the *ELEMENT_BEAM card (LS-Dyna), the 3rd node for the beam element is assigned with a random node id (but same coordinates as first node). Is there any possibility to replace the 3rd node id with the 1st node id?

    Hello @Ushay

     

    I think you can create beam with '*barelementcreatewithoffsets' command.

     

    *createvector 1 1 0 0
    *barelementcreatewithoffsets Node1 Node2 1 Node3 1 0 0 '' 0 0 0 0 0 0 0 0

     

    Thanks,

    Imoto

    Hello @Imoto,

     

    thanks for the reply. 

     

    It is not accepting the Node 1 and Node 3 to be the same.

    I am trying to make the nodes 1 and 3 the same, to get something like this for a beam element.
