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. (6.1). The linear static analysis is required, the influence of shear is neglected.

#only momentum influence to the displacements is taken into account
#beamShearCoeff is artificially enlarged.
