Reference solution
=====================

Travel
------------
Displacements in the center of solid :math:`A` are imposed in the directions :math:`x` and :math:`y` depending on time.
The trips are of the form:

.. math::
\ left\ {
        \ begin {aligned}
        D_x =\ sum_ {i}\ omega_ {x_i} sin (2\ pi f_ {x_i} t)\\
        D_y =\ sum_ {i}\ omega_ {y_i} sin (2\ pi f_ {y_i} t)
        \ end {aligned}
    \ right.



Uncertainty about solutions
------------------------------
It is a test case of non-regression. We test for non-regression.
