We present ane.ectivesystemforsimulating dust continuumobservationsby radiative transfersim-ulations. By using work.ow management system RENKEI-WFT, we utilized distributed computing resources and automated a sequence of computational tasks required for radiative transfer modeling, namely, mainradiativetransfersimulations,pre-/post-processes, anddatatransferbetween computing resources. Our system simultaneously executes a lot of radiative transfer simulations with di.erent input parameters on distributed computing resources. This capability of our system enables us to conduct e.ective research by radiative transfer simulation. As a demonstration of our system, we simulated dust continuum observations of protoplanetary disk. We performed hydrodynamic simula-tion modeling photoevaporating protoplanetary disk irradiated by ultra violet radiation from nearby massive stars. Results of this hydrodynamic simulation were used as input data for radiative transfer simulations. Expected spectral energy distributions and intensity maps were obtained by our system.
