Benchmark solution
=====================


Calculation method used for the reference solution
--------------------------------------------------------

Modeling A (2 DD_PLAN) is used as a reference for shell models.


Benchmark results
----------------------

Moves following :math:`\mathrm{Ox}` and :math:`\mathrm{Oy}` from point :math:`X` to :math:`\mathrm{mm}`.


Uncertainty about the solution
----------------------------

Experience shows that if you double the number of elements in both directions, the result varies by less than 2%.

The convergence criteria chosen must also make it possible to achieve the precision estimated for this 2D calculation: (2 or 3%).
