v3.01.403 SSLL403 - Buckling of a beam under the effect of its own weight

Summary:

This test makes it possible to validate the linear elasticity of the loading due to gravity forces for a modeling of the Euler straight beam type (POU_D_E). It also allows the implementation and validation of the calculation of the geometric rigidity matrix.

The reference solution is analytical and the results are considered satisfactory.
