The purpose of this test is to validate the use of load LIAISON_MAIL.

On the mesh represented by the figure above, the 3D part (modeled by 3D elements) and the surface part (modeled by Q4GG elements) are connected with kinematic links using LIAISON_MAIL/COQUE_MASSIF of the operator AFFE_CHAR_MECA. The faces of the 3D elements in :math:`x=0` are blocked and a force is imposed on a node located at the opposite end.

The calculation is done with STAT_NON_LINE. This provides an initial state for CALC_EUROPLEXUS. We do not impose on CALC_EUROPLEXUS any loads other than those that created the initial state.


Principle of validation
----------------------

Comparison with the initial state: it is considered that the load of type LIAISON_MAIL is considered to be well translated to EPX if the system remains in equilibrium, i.e. in the initial state provided.
