In ``dynamics``, an example of a dynamic simulation solved with an explicit time intergration is shown. This examples
model the propagation of a wave in a bar. The geometry is depicted in :numref:`fig-ex-dynamics_geom`. A pulse is impose
as an initial displacement over the bar. Results are depicted in :numref:`fig-ex-dynamics_displ`.
The explicit time integration scheme is set with:
.. code-block:: python
model.initFull(_analysis_method=aka._explicit_lumped_mass)
This example shows how to create a new functor to set the boundary conditions. This is done by creating a class that inherits from ``aka.FixedValue`` (``MyFixedValue(aka.FixedValue)`` in this case).
The boundary conditions are then applied with:
.. code-block:: python
model.applyBC(MyFixedValue(0, aka._x), "XBlocked")
model.applyBC(MyFixedValue(0, aka._y), "YBlocked")
