Hi guys,
I recently ran into a paper simulating pore-scale porous media with FVM-VOF model and then validated it with another numerical approach based on LBM named Shan-Chen LBM model and received more or less the same results; however, it did not mention anything about the pros and cons of these two approaches except that LBM is more flexible in dealing with complex geometries and boundary conditions than traditional FVM-VOF.
Has anyone got any clear idea and explanation of the difference between these two approaches, e.g, computational time or accuracy in capturing interface, etc?
Any helps or comments would be appreciated in advance
