   Structure: cantilever beam.
   Test objective: eigenfrequencies and eigenmodes calculated in a 
                   perturbation step following a static step with
                   temperature loading only. Due to the zero
                   expansion coefficient the loading creates 
                   displacements nor stresses, and the change of
                   frequencies compared to a nonperturbative step 
                   is only due to the lower Young's modulus at high 
                   temperature.
