Natural convection in a square cavity is simulated by multiple relaxation time (MRT) lattice Boltzmann method (LBM) with a separate distribution function to solve for the temperature distribution. The Rayleigh numbers examined range from Ra=103 to Ra=106. The simulations are performed for anisotropic thermal case and compared to isotropic thermal case.
