Efficient 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...
متن کاملRadiative Heat Transfer with Quasi Monte Carlo Methods
Monte Carlo simulation is often used to solve radiative transfer problems where complex physical phenomena and geometries must be handled. Slow convergence is a well known disadvantage of this method. In this paper we demonstrate that a significant improvement in computation time can be achieved by using Quasi-Monte Carlo (QMC) methods to simulate Rapid Thermal Processing.
متن کاملMonte 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 کاملEfficient Monte Carlo Methods for Cyclic Peptides
We present a new, biased Monte Carlo scheme for simulating complex, cyclic peptides. Backbone atoms are equilibrated with a biased rebridging scheme, and side-chain atoms are equilibrated with a look-ahead configurational bias Monte Carlo. Parallel tempering is shown to be an important ingredient in the construction of an efficient approach. Submitted to Molecular Physics.
متن کاملDiscrete Ordinates and Monte Carlo Methods for Radiative Transfer Simulation applied to CFD combustion modelling
Modelling radiative heat transfer in combustion applications involving complex geometries and detailed spectral properties of radiative gaseous species remains a difficult challenge, especially when full coupling with detailed chemistry and fluid dynamics is required. The Monte Carlo Method (MCM) usually considered as a reference ”exact” method for the computation of radiative transfer is howev...
