Spectral modeling of YSOs using continuum radiation is described. It is stressed that the most important step to obtain an accurate model SED is the radiative equilibrium calculations, though it is the most difficult part in modeling steps. Although there have been proposed and used several approximations to calculate the radiative equilibrium, another high accurate calculation method is needed for multi-dimensional, multi-frequency, and arbitrary optical depth problems. We have developed a new numerical method that can calculate the radiative equilibrium state in 2-D axially symmetric system. As an application of our method, we modeled the SED of a protostar L1551 IRS 5. We found that there seems to be a disk whose mass is about 0.3 Modot, that the frequency-dependence of the dust opacity in millimeter and sub-mm wavelength regions is 2, and the luminosity of the central star is 20 Lodot. In the future, in order to analyze observational data taken by high spatial resolution observations, accurate numerical calculation methods for multi-dimensional (2-D and 3-D) arbitrary optical depth problems will be more important.
