anigif_melt — Melting from below, as in basal magma ocean. Rayleigh = $$6 \cdot 10^{5}$$ , Stefan = 2 , Pr = 1

melt_red — Melting from above, as in a ice-melt ponds.

Made with our new Lattice Botlzmann “ch4-project” code.

Few years ago we simulated the same setup with a Pseudo-Spectral code. See the movie : bubbles
