Modeling the Elder problem with LBM

Dear All,

Thank you all for having this active and informative forum to help LBM newbies like me.

I have been working for a while on developing a LBM code for modeling the Elder problem (a classic benchmark problem in density-driven flow in macro scale porous media). I have used the model suggested by Thorne and Sukop : Lattice Boltzmann model for the elder problem. I have problem with getting the same results as them. My main issue is with the lattice units and physical units conversions. My question is has anyone tried to model the Elder problem with LBM using this approach or any other approach. I would really appreciate your comments and help.
