Abstract: We present the Astrophysical Multimessenger Modeling (AM$^3$) software. AM$^3$ is a documented open-sourcesoftware (source code at https://gitlab.desy.de/am3/am3; user guide and documentation at https://am3.readthedocs.io/en/latest/) that efficiently solves the coupled integro-differential equations describing the temporalevolution of the spectral densities of particles interacting in astrophysical environments, including photons,electrons, positrons, protons, neutrons, pions, muons, and neutrinos. The software has been extensively used tosimulate the multiwavelength and neutrino emission from active galactic nuclei (including blazars), gamma-raybursts, and tidal disruption events. The simulations include all relevant nonthermal processes, namely synchrotronemission, inverse Compton scattering, photon–photon annihilation, proton–proton and proton–photon pionproduction, and photo-pair production. The software self-consistently calculates the full cascade of primary andsecondary particles, including nonlinear feedback processes and predictions in the time domain. It also allows theuser to track separately the particle densities produced by means of each distinct interaction process, including thedifferent hadronic channels. With its efficient hybrid solver combining analytical and numerical techniques, AM3combines efficiency and accuracy at a user-adjustable level. We describe the technical details of the numericalframework and present three examples of applications to different astrophysical environments.
