Beam structure
--------------

This example for a simple beam structure gives basic overview of the
input file (found under tests/sm/beam2d_1.in). Structure geometry and
its constitutive and geometrical properties are shown in Fig.
(ex01_). The linear static analysis is required, the influence
of shear is neglected.

   Hovewer, the problem does not support the changes of static system.
   But it is possible to apply direct displacement control without
   requiring BC applied (see nrsolver documentation). Therefore it is
   possible to combine direct displacement control with direct load
   control or indirect control.
