Connecting Roll Cage to Carbon Fibre

Dear,

I am trying to connect the roll cage to our carbon fibre monocoque. But when I apply my loadcase (testing torsional stiffness). I get a big displacement of the roll cage. I simulate this cage by creating nodes, I connect these with a rigid to the carbon. The problem is that there is always one element of the rod that makes a huge displacement. I tried to remove the nodes and place them again, this didnt fix the problem. I don't know the reason why these displacments occur since I connect them with a rigid to the carbon.

 

I hope someone knows what occurs this problem and can help me.

    Hi,

     

    There are few modelling checks you need to carry on your model.

     

    1) Free 1D elements. 

    2) Duplicate elements

     

    In your model there are 5-10 free 1D elements are seen and few duplciate elements as well. Please check this and try again.
