**v3.04.007** SSLV07 - Stretching a parallelepiped under its own weight
===========================================================================

**Summary:**

This 3D static test makes it possible to validate the following functionalities:


* loading in its own weight (gravity or internal force) and in uniform pressure,


* calculation of the potential energy of the structure,


* residual error estimator (ModelingB)


* incompressible elements (D modeling).


* use of MACR_LIGN_COUP on a mult_elas concept (modeling A)

It includes 4 models. Its interest lies in highlighting the effect of the Poisson's ratio (transverse contraction).
