Efficient lattice Boltzmann models for the Kuramoto–Sivashinsky equation

•We improve the accuracy and stability of the lattice Boltzmann model for the Kuramoto–Sivashinsky equation proposed in [1]. This improvement is achieved by controlling the relaxation time, modifying the equilibrium state, and employing more and higher lattice speeds, in a manner suggested by our an...
