TriPoDPy simulates the evolution of gas and dust in protoplanetary disks using a parametric dust-evolution model. It models the radial evolution of disk material, including viscous evolution of the gas and the advection, diffusion, and growth of dust particles. It implements the TriPoD dust model to represent dust size distributions and track their evolution across the disk. The code uses Simframe (ascl:2603.018) for running simulations, and its Simulation class inherits attributes from DustPy (ascl:2207.016). TriPoDPy can be used to explore the structure and dynamics of protoplanetary disks and the processes that influence dust growth and transport during planet formation.
