Image domain
============

Overview
--------
This example uses the microsystem from the :doc:`../configuration_file` page,
``microsystem.png``, and the default ``parameters.toml``. The image is available
in the repository ``examples`` folder.

Command
-------

.. code-block:: console

   pymm -i microsystem.png -p parameters.toml -t all

Because ``image`` is the default mode and ``gmsh`` is the default executable,
no additional flags are required. The reported execution time was approximately
20 minutes.

Results
-------

.. figure:: ../figs/pressure.png
   :alt: Pressure field for the image-domain example

.. figure:: ../figs/velocity.png
   :alt: Velocity field for the image-domain example

.. figure:: ../figs/tracer.png
   :alt: Tracer concentration for the image-domain example

   Pressure, velocity, and tracer concentration.
