Hi,
I'm converting an Nastran model to LS-Dyna model.
I'm a new user, so I'm expertise about LS-Dyna software.
My problem consist about create an spring element with coincident nodes with a determinate degree of freedom.
In my nastran model I have used three CELAS2 (respectively with one degree of freedom per each) to simulate a spring element with stiffness in translational degree of freedom.
How can I make in LS-Dyna with ELEMENT-DISCRET? Where I have to specify the relative degree of freedom (like 1,2,3 or 4,5,6)? In SECTION_DISCRETE there is the 'DRO' parameters that one sets with 0 or 1, but without to specify the single specific DOF.
