Features

Coordinates and Grids

RADMC-3D features two kinds of coordinate systems:

• Cartesian coordinates 3-D: (x, y, z)

• Spherical coordinates 1-D: (r), 2-D: (r,θ), 3-D: (r, θ, φ)

It has the following gridding options:

• Regular cubic

• Variable grid spacing (spherical coordinates)

• Patch-wise refinement

• Full octree refinement

• Delaunay (branch: unstruct)

• Voronoi (branch: unstruct)

• Flexible unstructured (branch: unstruct)

Main physics modules

• Dust continuum: absorption/emission and scattering

• Polarized dust scattering

• Polarized dust thermal emission by aligned grains

• Atomic/molecular lines (LTE, local non-LTE: opt-thin, LVG, EscProb)

Radiation/energy sources

• Stars, positioned at will (either point sources or finite-size spheres)

• Continuous "star populations"

• Continuous internal heat source

• External radiation field

Imaging options

• Any viewing perspective, zoom-in factor, image pixels

• Observer at infinity or local observer

• Flux-conserving images, with recursive pixel refinement

• Multi-wavelength images

• Movie mode

Spectrum options

• SED on standard wavelength grid

• High-resolution spectrum on user-specified wavelength grid

• Aperture specification (spectrum of sub-region)

Miscellaneous

• Option to calculate mean intensity field (useful for coupling RADMC-3D to other radiative physics codes).

• OpenMP parallellization of the Monte Carlo modules.

• A Userdef module inside RADMC-3D to add user-defined functionality or internally generated models.

• VTK output for 3-D viewing of model setups
