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).
