TRAPHIC - Radiative Transfer for Smoothed Particle Hydrodynamics Simulations

Understand

We present TRAPHIC, a novel radiative transfer scheme for Smoothed Particle Hydrodynamics (SPH) simulations.

• TRAPHIC is designed for use in simulations exhibiting a wide dynamic range in physical length scales and containing a large number of light sources.
• It is adaptive both in space and in angle and can be employed for application on distributed memory machines.
• The commonly encountered computationally expensive scaling with the number of light sources in the simulation is avoided by introducing a source merging procedure.
