is a 3D Monte Carlo radiative transfer code that
-
allows to simulate intensity and polarization of light emerging from analytical astrophysical models as well as complex magneto-hydrodynamic simulations on various grids
-
is capable to perform dust heating, -emission, -scattering, -grain alignment, line radiative transfer, and synchrotron simulations
-
calculates synthetic intensity and polarization maps
-
makes use of a full set of physical quantities (density, temperature, velocity, magnetic field distribution, and dust grain properties as well as different sources of radiation) as input
The following packages are required for the installation:
-
gcc (preferred), icc, or clang++
-
cmake (preferred), or ninja
-
python3 (packages: numpy, setuptools)
Open a terminal/console and move into the POLARIS directory:
cd /YOUR/POLARIS/PATH/To install POLARIS, run the installation script:
./compile.sh -fFor the first installation, the option -f is required to install the cfitsio and CCfits libraries.
For more information, type:
./compile.sh -hPOLARIS can now be executed from any newly opened terminal/console. However, to use it in already open terminals/consoles, execute the following command to update the environmental paths:
source ~/.bashrcFor a guide how to run first simulations, please take a look in our quickstart.
For more information about POLARIS and its capabilities, please take a look in our manual.
