You cannot have pinned supports(Rx,Ry,Rz free) on one end of the bar and have Rx release(torsion) or rigid link Rz free at the other end.
But even fixing this at one of the bar ends will not make the combinations to converge for "large displacements " nonlinear analysis.
It will converge ,though , to Pdelta analysis alone
