A simple example of a beam of uniform cross-section area undergoing a transverse point force at its end while being clamped at the other end (where only flexion dof are free) reveals that the beam length increases with time. Its longitudinal deflection stays at zero at every s coordinate regardless of the transverse deflections.

This does not occur with the non-linear solver.
