We use the photoionisation and dust radiative transfer code MOCASSIN to
create a model of the dwarf irregular galaxy NGC 4449. The best-matching model
reproduces the global optical emission line fluxes and the observed spectral
energy distribution (SED) spanning wavelengths from the UV to sub-mm, and
requires the bolometric luminosity of 6.25e9 Lsolar for the underlying stellar
component, M_d/M_g of 1/680 and M_d of 2.2e6 Msolar.
