Reading and visualising MAS runs
================================

First, load the required modules.


.. code-block:: default

    from psipy.model import MASOutput
    import matplotlib.pyplot as plt








Load a set of MAS output files.


.. code-block:: default

    mas_path = '/Users/dstansby/github/psipy/data/helio'
    model = MASOutput(mas_path)








Each MAS model contains a number of variables. The variable names can be
accessed using the ``.variables`` attribute.


.. code-block:: default

    print(model.variables)





.. rst-class:: sphx-glr-script-out

 Out:

 .. code-block:: none

    ['p', 't', 'va', 'br', 'vp', 'jp', 'jr', 'bp', 'vr', 'bt', 'vt', 'rho', 'jt']




Plot a cut of the model at a constant radius


.. code-block:: default

    fig, ax = plt.subplots()
    model['rho'].plot_radial_cut(0, ax=ax)




.. image:: /auto_examples/images/sphx_glr_plot_visualising_mas_001.png
    :alt: rho, r=29.26$R_{\odot}$
    :class: sphx-glr-single-img





Plot a cut of the model at a constant longitude.


.. code-block:: default

    fig = plt.figure()
    ax = plt.subplot(111, projection='polar')
    model['rho'].plot_phi_cut(75, ax=ax)




.. image:: /auto_examples/images/sphx_glr_plot_visualising_mas_002.png
    :alt: rho, $\phi$= 210.94$^{\circ}$
    :class: sphx-glr-single-img





Add the current sheet


.. code-block:: default

    fig = plt.figure()
    ax = plt.subplot(111, projection='polar')
    model['rho'].plot_phi_cut(75, ax=ax)
    model['br'].contour_phi_cut(75, levels=[0], ax=ax, colors='white')
    plt.show()



.. image:: /auto_examples/images/sphx_glr_plot_visualising_mas_003.png
    :alt: rho, $\phi$= 210.94$^{\circ}$
