The example of input file for simple beam structure is presented.
Structure geometry and its constitutive and geometrical properties are
shown in fig. (1). The linear static analysis is required,
the influence of shear is neglected. Please note that one input line
which is too long to fit to page, is separated into two lines using
backslash '
' character, but OOFEM requires that it must be typed as one single line.

Simple Beam Structure - linear analysis
#only momentum influence to the displacements is taken into account
#beamShearCoeff is artificially enlarged.
