`Gmsh <http://geuz.org/gmsh/>`__ is a powerful mesh generation tool with
a scripting language that is notoriously hard to write.
The goal of PyGmsh is to combine the power of Gmsh with the versatility
of Python and to provide useful abstractions from the Gmsh scripting
language so you can create complex geometries more easily.

To create the above mesh, simply do
.. code:: python test
import pygmsh as pg
import numpy as np
geom = pg.Geometry()
# Draw a cross.
poly = geom.add_polygon([
[0.0, 0.5, 0.0],
[-0.1, 0.1, 0.0],
[-0.5, 0.0, 0.0],
[-0.1, -0.1, 0.0],
[0.0, -0.5, 0.0],
[0.1, -0.1, 0.0],
[0.5, 0.0, 0.0],
[0.1, 0.1, 0.0]
],
lcar=0.05
)
axis = [0, 0, 1]
geom.extrude(
poly,
translation_axis=axis,
rotation_axis=axis,
point_on_axis=[0, 0, 0],
angle=2.0 / 6.0 * np.pi
)
points, cells, point_data, cell_data, field_data = pg.generate_mesh(geom)
to retrieve all points and cells of the mesh for the specified geometry.
To store the mesh, you can use
`meshio <https://pypi.python.org/pypi/meshio>`__; for example
.. code:: python
import meshio
meshio.write('test.vtu', points, cells, cell_data=cell_data)
The output file can be visualized with various tools, e.g.,
`ParaView <http://www.paraview.org/>`__.
You will find the above mesh in the directory ``test/examples/`` along
with other small examples.
Installation
~~~~~~~~~~~~
PyGmsh is `available from the Python Package
Index <https://pypi.python.org/pypi/pygmsh/>`__, so simply type
::
pip install -U pygmsh
to install or upgrade.
Usage
~~~~~
Just
::
import pygmsh as pg
and make use of all the goodies the module provides. The
`documentation <http://pygmsh.readthedocs.org/>`__ and the examples
under
```test/examples/`` <https://github.com/nschloe/pygmsh/tree/master/test/examples>`__
might inspire you.
Testing
~~~~~~~
To run the PyGmsh unit tests, check out this repository and type
::
pytest
Distribution
~~~~~~~~~~~~
To create a new release
1. bump the ``__version__`` number,
2. publish to PyPi and GitHub:
::
$ make publish
