MOnte CArlo SimulationS of Ionised Nebulae
mocassin is a fully 3D or 2D photoionisation and dust radiative transfer code
which employs a Monte Carlo approach to the transfer of radiation through
media of arbitrary geometry and density distribution. It was originally
developed for the modelling of photoionised regions like HII regions and
planetary nebulae and has since expanded and been applied to a variety of
astrophysical problems, including modelling clumpy dusty supernova envelopes,
star forming galaxies, protoplanetary disks and inner shell fluorence emission
in the photospheres of stars and disk atmospheres. The code can deal with
arbitrary Cartesian grids of variable resolution, it has successfully been
used to model complex density fields from SPH calculations and can deal with
ionising radiation extending from Lyman edge to the X-ray. The dust and gas
microphysics is fully coupled both in the radiation transfer and in the
thermal balance.
