cuDisc simulates the evolution of protoplanetary discs in both the radial and vertical dimensions, assuming axisymmetry. The code performs 2D dust advection-diffusion, dust coagulation/fragmentation, and radiative transfer. A 1D evolution model is also included, with the 2D gas structure calculated via vertical hydrostatic equilibrium. cuDisc requires a NVIDIA GPU.

EvapMass predicts the minimum masses of planets in multi-planet systems using the photoevaporation-driven evolution model. The planetary system requires both a planet above and below the radius gap to be useful for this test. EvapMass includes an example Jupyter notebook for the Kepler-36 system. EvalMass can be used to identify TESS systems that warrant radial-velocity follow-up to further test the photoevaporation model.
