Lattice Boltzmann models for the convection-diffusion equation: D2Q5 vs D2Q9

•A direct comparison between the D2Q5 and D2Q9 LB models for the convection-diffusion equation is presented.•The main conclusion that D2Q5 is more robust and accurate than D2Q9 in general is supported with detailed numerical tests.•Similar conclusions are obtained in 3D by comparing D3Q7 and D3Q19.•...
