MESHFEM2D Parameter Documentation
=================================

SPECFEM++ uses a modified version of the mesher provided by the original
`SPECFEM2D <https://specfem2d.readthedocs.io/en/latest/03_mesh_generation/>`_
code. The modifications isolate only the necessary parameters for the meshing
process and remove those needed by the solver from the original ``Par_File``.
We document only the parameters that are used by the meshing process.
However you should also refer to the `SPECFEM2D documentation
<https://specfem2d.readthedocs.io/en/latest/03_mesh_generation/>`_ for a more
in-depth description of the mesher.

To define the meshing parameters, you will need to create a ``Par_File``. This
is a simple text file that contains the parameters you wish to use. The
parameters are defined in the following format:

.. code-block:: bash

    parameter_name = parameter_value
