ScatPy is a Python package for interfacing to the popular scattering simulator DDSCAT. ScatPy provides a rich toolset to:

• Create standard DDSCAT scattering targets based on physical (rather than dipole) dimensions
• Construct and visualize complex custom scattering targets
• Manage the job parameters found in the ddscat.par file
• Organize iterative jobs requiring multiple targets or input parameters
• Script job submission to cluster queue managers
• Maintain profiles and defaults for deployment on platforms other than the local machine
• Load, plot and manipulate DDSCAT output tables
• Manage the output from multiple jobs through results collections
• Work with and visualize nearfield results as multidimensional numpy arrays
• Suitable for interactive or scripted use

The package can be downloaded for installation via easy_install at https://pypi.python.org/pypi/ScatPy

    from ScatPy import *

    # Establish target geometry (in um)
    length = 0.100
    radius = 0.020
    target = targets.CYLNDRCAP(length, radius, d=0.005, material='Au_Palik.txt')

    # Create a job to be run in the subdirectory tmp/
    job = DDscat(folder = './tmp', target=target)

    # Change the range of calculated wavelengths and ambient index
    job.settings.wavelengths = ranges.How_Range(0.300, 0.600, 15)
    job.settings.NAMBIENT = 1.0

    # Run the job locally
    job.calculate()

    # Open the results qtable, plot Q_sca, and Q_abs, and add a legend
    ans = results.QTable(folder = './tmp')
    ax = ans.plot(['Q_sca', 'Q_abs'])
    ax.legend(loc=0)
