Example 11, Slide 12: Lowest buckling mode from the STAGS finite element model shown in the previous slide

Fig. 21 from the 2014 GENOPT paper.
General buckling from STAGS. This general buckling mode is symmetric at the symmetry plane at x = WIDTH/2. There is very good agreement of both the buckling load factor and buckling mode shape predicted by STAGS and by GENOPT/BIGBOSOR4
