In ``plate_hole``, an example of a static solution of a loaded plate with a hole. Because of the symmetries, only a quarter of the problem is modeled. The corresponding domain and boundary conditions is shown in :numref:`fig-ex-plate_hole`.
The static solver is initialized with:
.. code-block:: python
model.initFull(_analysis_method=aka._static)
Boundary conditions are applied with:
.. code-block:: python
model.applyBC(aka.FixedValue(0.0, aka._x), "XBlocked")
model.applyBC(aka.FixedValue(0.0, aka._y), "YBlocked")
model.applyBC(aka.FromTraction(trac), "Traction")
where ``trac`` is a numpy array of size ``spatial_dimension``.
Additionally, the simulation can be run in parallel. To do so, the following lines are added:
.. code-block:: python
try:
from mpi4py import MPI
comm = MPI.COMM_WORLD
prank = comm.Get_rank()
except ImportError:
prank = 0
Similarly to C++, the mesh has to be distributed between the processors with::
mesh.distribute()
.. _fig-ex-plate_hole:

:align: center

The displacement magnitude is displayed in :numref:`fig-ex-plate_hole_displ`.
