Schematic showing a high-level view of the code architecture of POWDERDAY. POWDERDAY interfaces with a broad range of hydrodynamic galaxy evolution codes, regularizing them into a common format. The stellar population synthesis is done on the fly with FSPS and thus offers significant run-time flexibility. Similar levels of flexibility exist with the dust grid generation, including the ability to use the outputs from newer on-the-fly dust evolution models in cosmological simulations. Finally, the dust radiative transfer is performed with the HYPERION Monte Carlo dust radiative transfer code. Throughout the entire code flow, POWDERDAY depends on YT as a glue connecting a wide range of modules.
