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


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

This problem does not have a reference solution.

Modeling A is used as a reference for modeling B.


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

Moves :math:`u` and :math:`v` to points :math:`\mathit{P1}`, :math:`\mathrm{P2}`, :math:`\mathrm{P3}`, :math:`\mathrm{P4}`.


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

The "reference" solution depends on the spatial discretization of the model; this is why the mesh is drawn in [:ref:`§1.1 <§1.1>`].

Modeling B must respect this mesh to lead to the same results as A.
