Hi Ben,

I suggest you build a small model with just few beam elements and verify the dynain workflow. 

Dynain does not import geometry but only imports the mesh, i.e. the nodal coordinates and elements, the *INITIAL_STRESS keyword, and the *BOUNDARY_SPC keyword. Everything else should be redefined in WB.

If for some reason this approach does not work well with beam element, you may try with the LS-DYNA Restart module.

I hope this helps.
