How to apply torsional spring in Workbench?
I'm creating a simulation in which I want to restrain all degrees of freedom of a vertex with spring elements (springs needed for post-processing). Essentially, I'm looking to replicate a Nastran CBUSH element with stiffness values applied to all 6 DOF. My plan was to apply 3 springs, each with an appropriate longitudinal and torsional stiffness; however, when I insert a spring in Workbench, it defaults to a longitudinal spring and does not allow any modifications or implementation of torsional stiffness.
Is there a way that torsional stiffness can be added to longitudinal springs in Workbench? Alternatively, is there a more efficient way to restrain all six DOF at a vertex using joints (one that would still allow me to probe reaction forces and moments)? I would be grateful for any suggestions!
