Reference problem
=====================


Geometry
---------

The geometry of the problem is irrelevant. You just need to know that the mesh contains at least:


* 3 named stitches: :math:`\mathit{M1}`, :math:`\mathit{M2}` and :math:`\mathit{M3}`,


* 3 named nodes: :math:`\mathit{A1}`, :math:`\mathit{A2}` and :math:`\mathit{A3}`.


Material properties
----------------------

Unimportant. We chose the VMIS_ISOT_CINE law of behavior, which has at least 3 internal variables.


Boundary conditions and loads
-------------------------------------

Unimportant.


Initial conditions
