Viewing data generated by AWS Palace
====================================

The Palace simulation API produces ``.pvd`` and ``.vtu`` files corresponding to the field data. This can be viewed via *Paraview* or the in-built utility as follows:

.. code-block:: python

    from SQDMetal.PALACE.PVDVTU_Viewer import PVDVTU_Viewer

    data_path = 'output_example/paraview/eigenmode/eigenmode.pvd'

    #Create the viewer object from the generated datasets
    leView = PVDVTU_Viewer(data_path)

    #Create a 2D slice of the 3D dataset
    leSlice = leView.get_data_slice(data_set_index=0, slice_plane_normal=np.array([0,0,1]), slice_plane_origin=np.array([0,0,0]))

    #Gather and plot the magnitude of the z-component of the electric field: E_z
    data = leSlice.get_data('E_real')[:,2]
    fig = leSlice.plot(data, 'coolwarm', True)

    #Gather and plot the magnitude of the electric field: |E|
    data = np.linalg.norm(leSlice.get_data('E_real'), axis=1)
    fig = leSlice.plot(data, 'coolwarm', True)
