Torch

Torch is a software aggregate of multiple codes combined through the Astrophysical Multipurpose Software Environment (AMUSE). The method combines the magnetohydrodynamics code FLASH, including the ray-tracing radiation module FERVENT, with N-body dynamics code petar, and stellar evolution SeBa. This enables Torch to simulate the formation of star clusters from gas clouds, including the collapse of magnetised gas, formation and evolution of individual and systems of multiple stars (including primordial binaries), their N-body dynamics and feedback processes, the latter of which eventually clear the system of the remaining gas, leaving only the star cluster.

Torch works by using a kick-drift-kick scheme and a bridge between the different codes to communicate the evolutionary steps of different physical processes.

Torch has been used in many scientific papers. An up-to-date list is maintained on ADS.
