v3.05.100 SSLX100 - 3D mix - Shell - Bending beam

Summary:

This test makes it possible to validate for a linear elastic calculation:

• a mixture of different mechanical models: 3D model (element HEXA20), shell models (elements DKT, or elements COQUE_3D) and beam model (elements POU_D_E),

• linear relationships between degrees of freedom, built in particular with the connections [R3.03.03] and [R3.03.06].

The test is based on the elastic analytical solution of a bending beam. The reduced number of elements for the various models leads to a mediocre solution, which is however significantly improved with the use of boundary conditions appropriate to the theory of beams.
