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

This example for a simple beam structure gives basic overview of the
input file (found under ``tests/regression/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.
