Monte Carlo radiative transfer in protoplanetary disks
Aims. We present a new continuum 3D radiative transfer code, MCFOST, based on a Monte-Carlo method. MCFOST can be used to calculate (i) monochromatic images in scattered light and/or thermal emission, (ii) polarisation maps, (iii) interferometric visibilities, (iv) spectral energy distributions and (v) dust temperature distributions of protoplanetary disks. Methods. Several improvements to the ...
متن کاملMonte Carlo Radiative Heat Transfer Simulation on a Reconfigurable Computer
Recently, the appearance of very large (3 – 10M gate) FPGAs with embedded arithmetic units has opened the door to the possibility of floating point computation on these devices. While previous researchers have described peak performance or kernel matrix operations, there is as yet relatively little experience with mapping an application-specific floating point loop onto FPGAs. In this work, we ...
متن کاملA Study of Monte Carlo Radiative Transfer Through Fractal Clouds
Introduction An understanding of radiation transport (RT) through The goal of this experiment is to simulate radiation clouds is fundamental to studies of the earth’s radiation budget and climate dynamics. The transmission through horizontally homogeneous clouds has been studied thoroughly using accurate, discreet ordinates radiative transfer models. However, the applicability of these results ...
متن کاملRadiative Equilibrium and Temperature Correction in Monte Carlo Radiation Transfer
We describe a general radiative equilibrium and temperature correction procedure for use in Monte Carlo radiation transfer codes with sources of temperature-independent opacity, such as astrophysical dust. The technique utilizes the fact that Monte Carlo simulations track individual photon packets, so we may easily determine where their energy is absorbed. When a packet is absorbed, it heats a ...
متن کاملEfficient Monte Carlo methods for continuum radiative transfer
We discuss the efficiency of Monte Carlo methods in solving continuum radiative transfer problems. The sampling of the radiation field and convergence of dust temperature calculations in the case of optically thick clouds are both studied. For spherically symmetric clouds we find that the computational cost of Monte Carlo simulations can be reduced, in some cases by orders of magnitude, with si...
