A radiative-convective model for lava planet atmospheres

A numerical model for the atmospheres of hot rocky (exo)planets. AGNI's primary purpose is to simulate the evolving atmospheres of magma ocean planets, while ensuring that radiative-convective equilibrium is sufficiently maintained. Pronounced as ag-nee. Named after the fire deity of Hinduism.
